Child Abuse Imaging Indian Medical PG Practice Questions and MCQs
Practice Indian Medical PG questions for Child Abuse Imaging. These multiple choice questions (MCQs) cover important concepts and help you prepare for your exams.
Child Abuse Imaging Indian Medical PG Question 1: A child presents with poor growth and swelling at joints. A radiograph of his wrist is given below. Lab investigations reveal serum ALP levels of >1500. What is the possible diagnosis?
- A. Rickets (Correct Answer)
- B. Osteoporosis
- C. Osteomalacia
- D. Osteogenesis imperfecta
Child Abuse Imaging Explanation: ***Rickets***
- The combination of **poor growth**, **joint swelling**, and **elevated alkaline phosphatase (ALP)** in a child strongly indicates rickets, a condition of defective bone mineralization in growing bones.
- The radiograph of the wrist would likely show typical findings like **widened growth plates**, **fraying** and **cupping of metaphyses**, and **decreased bone density**, which are characteristic of rickets.
*Osteoporosis*
- This condition is characterized by **reduced bone mass** and **fragile bones**, typically seen in older adults or due to secondary causes, and is not primarily linked to joint swelling in children.
- While ALP levels can be normal or slightly elevated in osteoporosis, a level of >1500 is highly suggestive of active bone formation or breakdown, not typically seen in osteoporosis.
*Osteomalacia*
- This is defective bone mineralization in adults after growth plates have fused, leading to **bone softening** and **pain**, typically not presenting with joint swelling as a primary symptom.
- While it also involves high ALP and bone demineralization, the clinical context of a *child* with growth issues points more specifically to rickets.
*Osteogenesis imperfecta*
- This is a group of **genetic disorders** characterized by **brittle bones** that fracture easily, often accompanied by **blue sclerae** and **hearing loss**, which are not mentioned in the presentation.
- While bone fragility is present, it does not typically cause the described joint swelling or the significantly elevated ALP levels seen in this case.
Child Abuse Imaging Indian Medical PG Question 2: What is the investigation of choice for diagnosing a stress fracture?
- A. X-ray
- B. CT scan
- C. MRI (Correct Answer)
- D. Bone scan
Child Abuse Imaging Explanation: ***MRI***
- **Magnetic Resonance Imaging (MRI)** is the most sensitive and specific imaging modality for diagnosing **stress fractures**, especially in their early stages.
- It can detect **bone marrow edema** and **periosteal reactions** indicative of stress injury before cortical changes are visible on plain radiographs.
*X-ray*
- **X-rays** are often the initial investigation, but they have low sensitivity for **stress fractures** in the early stages as bone changes may not be apparent for several weeks.
- A positive X-ray for stress fracture typically shows a **sclerotic line** or **periosteal reaction**, but this indicates a more advanced injury.
*CT scan*
- **CT scans** provide excellent detail of **cortical bone** and can detect subtle fractures not seen on X-rays.
- While more sensitive than X-rays, CT has **higher radiation exposure** and is generally less sensitive than MRI for early detection of **bone marrow edema** associated with stress injuries.
*Bone scan*
- **Bone scans** (scintigraphy) are highly sensitive for detecting increased **osteoblastic activity** associated with stress fractures.
- However, they are **less specific** as various conditions can cause increased uptake, and they do not provide detailed anatomical information, making MRI superior for definitive diagnosis and staging.
Child Abuse Imaging Indian Medical PG Question 3: A patient is brought to the emergency following a head-on collision road traffic accident. His BP is 90/60 mmHg. Tachycardia is present. Most likely diagnosis is
- A. SDH
- B. EDH
- C. Intra-abdominal bleeding (Correct Answer)
- D. Intra cranial hemorrhage
Child Abuse Imaging Explanation: ***Intra-abdominal bleeding***
- Following a **head-on collision**, hypotension (BP 90/60 mmHg) and tachycardia are classic signs of **hypovolemic shock**, most commonly due to significant internal bleeding.
- The **abdomen** is a common site for massive blood loss after blunt trauma, as it can contain large volumes of blood without obvious external signs.
*SDH (Subdural Hematoma)*
- While a subdural hematoma can occur after head trauma, significant **intracranial bleeding** typically causes signs of increased intracranial pressure (e.g., headache, altered mental status, neurological deficits), and often leads to **hypertension with bradycardia** (Cushing's reflex), not hypotension and tachycardia.
- The primary hemodynamic response to an isolated SDH would not be profound hypotension and tachycardia unless there was a co-existing systemic injury.
*EDH (Epidural Hematoma)*
- An epidural hematoma is also an intracranial injury that causes signs of **increased intracranial pressure**, such as headache, vomiting, and a potential "lucid interval."
- Like SDH, it would not typically cause **hypotension and tachycardia** as the primary hemodynamic response, as it does not lead to significant blood loss from the circulatory system.
*Intracranial hemorrhage*
- This is a general term for bleeding within the skull, encompassing conditions like SDH and EDH.
- While it is a severe injury, isolated intracranial hemorrhage generally does not cause **hypotension and tachycardia** because the cranial vault has limited space, and therefore, blood loss is not sufficient to produce systemic shock. Instead, it often leads to signs of **increased intracranial pressure** including **hypertension and bradycardia**.
Child Abuse Imaging Indian Medical PG Question 4: A man presents to the emergency department with a head injury following a vehicular accident. What is the investigation of choice?
- A. MRI
- B. CECT
- C. NCCT (Correct Answer)
- D. X-ray
Child Abuse Imaging Explanation: ***NCCT***
- **Non-contrast Computed Tomography (NCCT)** of the head is the **investigation of choice** for acute head trauma due to its rapid acquisition, wide availability, and excellent sensitivity for detecting acute hemorrhage, fractures, and mass effects.
- It rapidly identifies life-threatening conditions such as **epidural, subdural, and intracerebral hemorrhages**, which require immediate intervention.
*MRI*
- **MRI** is superior for detecting subtle brain tissue injuries, diffuse axonal injury, and non-hemorrhagic lesions but is generally **not the first-line investigation** in acute trauma due to longer scan times, limited availability in the emergency setting, and inability to detect acute hemorrhage as clearly as CT.
- Its use is typically reserved for follow-up studies or when CT findings are inconclusive or specific soft tissue detail is required.
*CECT*
- **Contrast-enhanced CT (CECT)** of the head is reserved for specific indications like evaluating vascular lesions (e.g., aneurysms, arteriovenous malformations) or tumors, which are generally **not the primary concern** in the initial assessment of acute head trauma.
- Administering contrast agents can delay imaging, may pose risks to patients with renal impairment or allergies, and does not significantly improve the detection of acute traumatic hemorrhage compared to NCCT.
*X-ray*
- **X-rays** of the skull are useful for detecting **skull fractures**, but they provide **limited information** regarding intracranial injuries or soft tissue damage, which are critical in head trauma.
- They have largely been superseded by CT scans, which offer a more comprehensive view of both bony structures and intracranial contents.
Child Abuse Imaging Indian Medical PG Question 5: Which of the following is a characteristic feature of Battered Baby Syndrome (Non-Accidental Injury)?
- A. Stab injury
- B. Firearm injury
- C. Bruises of varying ages (Correct Answer)
- D. None of the options
Child Abuse Imaging Explanation: ***Bruises of varying ages***
- The presence of bruises at **different stages of healing** is a hallmark indicator of **non-accidental trauma** or Battered Baby Syndrome, as it suggests repeated injuries occurring over time rather than a single incident.
- **Forensic significance**: Fresh bruises (red/purple) alongside older bruises (yellow/green/brown) indicate multiple episodes of trauma, which is inconsistent with the caregiver's explanation of a single accidental event.
- Other classic features include fractures (especially metaphyseal/corner fractures, rib fractures), subdural hematomas, retinal hemorrhages, and injuries in protected body areas.
*Stab injury*
- While a stab injury represents severe trauma requiring forensic investigation, it is **not characteristic** of the typical presentation pattern of Battered Baby Syndrome.
- Stab wounds indicate a specific violent act rather than the pattern of **repeated blunt force trauma** that defines the syndrome.
- Battered Baby Syndrome classically involves injuries from shaking, hitting, or blunt trauma rather than penetrating injuries.
*Firearm injury*
- A firearm injury is a distinct acute traumatic event that does not represent the **chronic, repetitive abuse pattern** seen in Battered Baby Syndrome.
- Such injuries are typically isolated incidents rather than part of ongoing physical abuse with varied injury ages.
- The syndrome is characterized by multiple injuries at different healing stages from repeated episodes, not single penetrating trauma.
*None of the options*
- This option is incorrect because "bruises of varying ages" is a **well-established forensic indicator** for diagnosing Battered Baby Syndrome in medical literature and practice.
- The presence of injuries at multiple stages of healing is one of the most important diagnostic features that raises suspicion for non-accidental injury in pediatric forensic medicine.
Child Abuse Imaging Indian Medical PG Question 6: An intrauterine scan at the 13th week of pregnancy showed a fetus with multiple long bone fractures. What is commonly associated with this finding?
- A. Osteogenesis imperfecta (Correct Answer)
- B. Marfan syndrome
- C. Achondroplasia
- D. Cretinism
Child Abuse Imaging Explanation: ***Osteogenesis imperfecta***
- **Multiple long bone fractures** detected early in pregnancy are a classic presentation of **osteogenesis imperfecta (OI)**, a genetic disorder characterized by **bone fragility**.
- OI is primarily caused by mutations in genes encoding **type I collagen**, leading to defective bone formation.
*Achondroplasia*
- This condition is a form of **dwarfism** characterized by disproportionately short limbs and a normal-sized trunk, resulting from a mutation in the **FGFR3 gene**.
- While it affects bone growth, it typically does not cause **multiple fractures** prenatally.
*Marfan syndrome*
- This is a connective tissue disorder affecting the skeletal, ocular, and cardiovascular systems, characterized by **tall stature**, **long limbs and fingers**, and **aortic root dilation**.
- It results from a mutation in the **fibrillin-1 gene** and is not primarily associated with prenatal long bone fractures.
*Cretinism*
- This is a historical term for **congenital hypothyroidism**, which results from severely deficient thyroid hormone production in a newborn.
- It leads to developmental delays, growth retardation, and intellectual disability, but not to **multiple bone fractures**.
Child Abuse Imaging Indian Medical PG Question 7: A young child presented with mild intermittent upper abdominal pain. X-ray is given below. What is the diagnosis?
- A. Morgagni hernia (Correct Answer)
- B. Bochdalek hernia
- C. Gastric volvulus
- D. Eventration of diaphragm
Child Abuse Imaging Explanation: ***Morgagni hernia***
- The X-ray shows a **gas-filled lesion** in the **right cardiophrenic angle**, which is characteristic of a Morgagni hernia, where abdominal contents (often colon or omentum) herniate through the foramen of Morgagni.
- The mild intermittent **upper abdominal pain** in a child is consistent with the infrequent or non-specific symptoms these hernias can present, as they are often discovered incidentally.
*Bochdalek hernia*
- **Bochdalek hernias** typically occur posteriorly and laterally, predominately on the **left side**, and are usually identified in the **neonatal period** with severe respiratory distress.
- The radiographic appearance would be of abdominal contents (bowel loops, liver, spleen) largely filling the ipsilateral hemithorax, causing significant mediastinal shift, which is not seen here.
*Gastric volvulus*
- **Gastric volvulus** involves abnormal rotation of the stomach, often presenting with acute symptoms like **epigastric pain, vomiting, and inability to pass a nasogastric tube (Borchardt's triad)**.
- Radiographically, it would show a **distended stomach** with an abnormal position, often high in the chest, but without the distinct localized air-filled mass in the cardiophrenic angle.
*Eventration of diaphragm*
- **Diaphragmatic eventration** is an abnormal elevation of part or all of an intact hemidiaphragm, usually due to muscular hypoplasia.
- The X-ray would show a **uniformly elevated hemidiaphragm** with normal continuity, and there would be no discrete air-filled structures above the diaphragm to suggest herniated bowel.
Child Abuse Imaging Indian Medical PG Question 8: Shape of extradural hematoma on NCCT is?
- A. Bean shaped
- B. Crescent shaped
- C. Lens shaped (Correct Answer)
- D. Medially concave
Child Abuse Imaging Explanation: ***Lens shaped***
- An **extradural hematoma** (EDH) appears **biconvex** or **lens-shaped** because it is limited by the cranial sutures, where the dura mater is tightly attached to the inner table of the skull.
- This characteristic shape helps differentiate it from other intracranial hemorrhages on **non-contrast CT (NCCT)** scans.
*Bean shaped*
- While descriptive, "bean-shaped" is not the standard or most accurate descriptor for an EDH, which is typically more organized and sharply delineated due to its confinement.
- This term might be loosely applied to other lesions but lacks the precision needed for a confident diagnosis of EDH.
*Crescent shaped*
- A **crescent shape** is characteristic of a **subdural hematoma (SDH)**, which spreads more freely over the brain surface as it is located between the dura and arachnoid mater, not limited by sutures.
- This shape indicates bleeding across suture lines, a key differentiator from EDH.
*Medially concave*
- This describes the typical appearance of a **subdural hematoma** (SDH), where the collection of blood conforms to the curvature of the brain surface and can extend across suture lines.
- An EDH is typically **convex** towards the brain parenchyma because of the dura's adherence to the skull at the sutures.
Child Abuse Imaging Indian Medical PG Question 9: The following X-ray is used to evaluate \qquad sinus?
- A. Frontal
- B. Maxillary (Correct Answer)
- C. Ethmoidal
- D. Sphenoidal
Child Abuse Imaging Explanation: ***Maxillary***
- The image provided is a **Waters' view** (occipitomental view) X-ray of the paranasal sinuses, which is primarily used to visualize the **maxillary sinuses**.
- In a Waters' view, the **petrous ridges** (dense bone at the base of the skull) are projected below the maxillary sinuses, allowing for a clear view of these sinuses.
*Frontal*
- While the **frontal sinuses** are visible in a Waters' view, they are generally better visualized in a **Caldwell view** (occipitofrontal view) or lateral view.
- In this projection, their visualization can be obscured by other bony structures, and they are not the primary focus.
*Ethmoidal*
- The **ethmoidal sinuses** are typically comprised of multiple small air cells located between the orbits and are best seen on a **Caldwell view** or specialized oblique views.
- In a Waters' view, their evaluation is limited due to superimposition of other facial bones.
*Sphenoidal*
- The **sphenoidal sinuses** are located deep within the skull, inferior to the sella turcica, and are quite difficult to visualize on standard plain radiographs like the Waters' view.
- They are best assessed using a **lateral view of the skull** or advanced imaging like **CT scans**.
Child Abuse Imaging Indian Medical PG Question 10: A 35-year-old male with history of 4 weeks of immobilization for fracture of femur develops sudden onset breathlessness and blood in sputum. CT angiography shows? (Recent NEET Pattem 2018-19)
- A. Acute cor-pulmonale (Correct Answer)
- B. Pulmonary oedema
- C. Aortic dissection
- D. Fat embolism
Child Abuse Imaging Explanation: ***Acute cor-pulmonale***
- **4 weeks of immobilization** is a major risk factor for **deep vein thrombosis (DVT)** leading to **pulmonary embolism (PE)**
- **CT pulmonary angiography** is the gold standard investigation for PE, showing filling defects in pulmonary arteries
- Massive or submassive PE causes acute **right ventricular strain** = **acute cor-pulmonale**
- Clinical presentation of **sudden breathlessness** and **hemoptysis** is classic for pulmonary thromboembolism
- The timing (4 weeks post-immobilization) fits thromboembolism, not fat embolism
*Fat embolism*
- Occurs **acutely within 24-72 hours** after long bone fracture (especially femur/tibia)
- The **4-week delay** makes fat embolism extremely unlikely
- Presents with **respiratory distress, petechial rash, and neurological symptoms** (Gurd's criteria)
- CT findings show diffuse ground-glass opacities, not typical filling defects seen on CT angiography
*Pulmonary oedema*
- Caused by **left heart failure** or **ARDS**, showing bilateral interstitial and alveolar fluid
- Would show diffuse bilateral infiltrates on imaging, not filling defects in pulmonary vessels
- **Hemoptysis** is uncommon in cardiogenic pulmonary edema
- No clear cardiac history or precipitant in this patient
*Aortic dissection*
- Involves a tear in the aortic intima with blood dissecting through the aortic wall
- Presents with **sudden severe chest/back pain**, not primarily with hemoptysis
- CT angiography would show **aortic flap and false lumen**, not pulmonary vascular abnormalities
- Unrelated to femur fracture or prolonged immobilization
