NEET-PG 2017 Practice Questions

Q: A 30-year-old AIDS patient presents with complaints as shown below. All are true about the condition except?

Benign tumor. ***Benign tumor*** - **Kaposi's sarcoma** is a **malignant vascular tumor** characterized by abnormal proliferation of endothelial cells, making the statement that it's a benign tumor incorrect. - The lesions shown in the image (purplish-red to brownish plaques and nodules on the lower leg, typical in an AIDS patient) are highly suggestive of Kaposi's sarcoma, which is definitively not benign. *Vascular tumor* - **Kaposi's sarcoma** is indeed a **vascular tumor** that arises from endothelial cells and is characterized by the formation of new blood vessels. - The appearance of the lesions in the image, with their characteristic color and nodular/plaque-like morphology, is consistent with their vascular origin. *Not seen in transfusion related AIDS* - **Kaposi's sarcoma** can occur in individuals with **AIDS resulting from any mode of transmission**, including transfusion-related AIDS, as it is linked to the immunosuppression caused by HIV, not the specific mode of acquisition. - While it's more commonly associated with certain risk groups (e.g., homosexual men), the underlying immunosuppression is the key factor, meaning it can manifest regardless of how HIV was acquired. *HHV 8* - **Kaposi's sarcoma** is strongly associated with and considered a B-cell lymphotropic infection caused by the **Human Herpesvirus 8 (HHV-8)**, also known as Kaposi's sarcoma-associated herpesvirus (KSHV). - HHV-8 infection is a prerequisite for the development of Kaposi's sarcoma, particularly in immunocompromised individuals like those with AIDS.

Q: A patient presents with abdominal pain, diarrhea and weight loss. He gives past history of pulmonary TB. Barium film of the patient indicates which of the following condition?

Pulled up cecum. ***Pulled up cecum*** - The barium study shows an **abnormally high position** of the cecum, often caused by **adhesions** or **inflammatory processes** from previous infections like TB. - The **String sign of Kantor** (narrowed bowel segments appearing as thin strings) indicates **inflammatory bowel involvement**, commonly seen in **TB enteritis** or **Crohn's disease**. *Intestinal obstruction* - Would show **dilated bowel loops** proximal to the obstruction with **air-fluid levels** and minimal contrast passage beyond the blockage. - The radiological findings described (pulled up cecum and string sign) do not indicate mechanical obstruction. *Intestinal perforation* - Would demonstrate **extraluminal contrast leak** into the peritoneal cavity on barium study, which is not present here. - Clinical presentation would be **acute peritonitis** with severe pain and signs of sepsis, not chronic symptoms. *Diverticulum formation* - Would show **sac-like outpouchings** (diverticula) from the bowel wall, which are **not visualized** on this barium study. - The described findings of **string sign** and **cecal displacement** are inconsistent with diverticular disease.

Q: Which of the following is true regarding this condition?

Needle aspiration yields fluid that does not coagulate. ***Needle aspiration yields fluid that does not coagulate*** - The image depicts a large, translucent, fluid-filled cystic mass, characteristic of a **cystic hygroma** (lymphatic malformation). - Aspiration of a cystic hygroma typically yields **clear to straw-colored fluid** that is rich in protein but **does not coagulate** because it is lymphatic fluid, not blood. *Most common site is anterior triangle neck* - While cystic hygromas most commonly occur in the **neck**, they are typically found in the **posterior triangle**, not the anterior triangle. - The lesion in the image appears to be a large, diffuse cystic mass extending from the neck into the mediastinum or axilla. *It is due to vascular malformation* - This condition is a **lymphatic malformation**, specifically a cystic hygroma, not a vascular malformation. - **Vascular malformations** involve blood vessels and would typically present with different characteristics, such as being compressible and potentially blanching. *Usually decreases on crying* - Crying or straining typically **increases the size** of a cystic hygroma due to increased intrathoracic pressure, which impedes lymphatic flow and causes distention of the lymphatic sacs. - This characteristic helps differentiate it from conditions that might decrease in size with pressure. *Typically appears after 5 years of age* - Cystic hygromas are **congenital malformations** that are usually present at birth or become apparent within the **first 2 years of life** (approximately 90% by age 2). - Late presentation after 5 years of age is uncommon and would be unusual for this condition.

Q: A 22-year-old female patient complains of discharge from the neck along with a previous history of midline neck swelling. Image of the patient is given below. All the statements regarding this patient are true except:

It is a complication of nodular goiter. ***It is a complication of nodular goiter*** - A **thyroglossal duct cyst** is a congenital anomaly resulting from the incomplete obliteration of the thyroglossal duct, a remnant of thyroid gland development. - While it can become infected or form a fistula, it is not a complication of an acquired thyroid condition like **nodular goiter**, which is an enlargement of the thyroid gland. *This is thyroglossal fistula* - The patient's history of a **midline neck swelling** with **discharge from the neck** is highly suggestive of an infected thyroglossal duct cyst that has ruptured or been incised, forming a thyroglossal fistula. - A fistula is an **abnormal tract** connecting an internal cavity to the surface, in this case, the remnant of the thyroglossal duct to the skin. *Sistrunk's operation is the treatment of choice* - The **Sistrunk procedure** involves excising the thyroglossal duct cyst along with the central portion of the hyoid bone and the core of muscle extending to the foramen cecum at the base of the tongue. - This extensive removal is necessary due to the embryological origin and the high risk of recurrence if any part of the duct system, especially near the hyoid bone, is left behind. *This discharge site will move upwards on protrusion of tongue* - The **thyroglossal duct** travels through the hyoid bone and is embryologically connected to the tongue. - Therefore, structures within the persistent thyroglossal track, including a fistula, will move upwards with the **protrusion of the tongue**, which is a classic diagnostic sign.

Q: All of the following are true regarding this picture except: (Recent NEET Pattern 2016-17)

Usually bilateral. ***Usually bilateral*** - Paget's disease of the nipple, as depicted in the image (lesions on the nipple with surrounding dermatitis-like changes), is almost always an **unilateral condition**. - Its bilateral occurrence is exceedingly rare and would suggest a different or coincidental pathology. - **This is the FALSE statement** - Paget's disease is typically unilateral, not bilateral. *Associated with underlying invasive carcinoma of breast* - **Paget's disease of the nipple** is histologically characterized by the presence of **Paget cells** (adenocarcinoma cells) in the epidermis of the nipple and areola [2]. - In a vast majority of cases (90-95%), it is associated with an underlying **ductal carcinoma in situ (DCIS)** or an **invasive ductal carcinoma** originating from the lactiferous ducts [1], [2]. *Itching is a common symptom* - **Itching (pruritus)** is a **prominent and common symptom** of Paget's disease of the nipple, along with burning, pain, and crusting. - The eczematous changes often lead to significant discomfort and itching. *Treatment is simple mastectomy with axillary lymph node dissection* - The standard treatment for Paget's disease of the nipple, especially when associated with an underlying invasive carcinoma, is **surgical excision**. - A **simple mastectomy** removes the entire breast and is often combined with **axillary lymph node dissection** or sentinel lymph node biopsy to assess for nodal involvement [1]. **References:** [1] Cross SS. Underwood's Pathology: A Clinical Approach. 6th ed. Common Clinical Problems From Liver And Biliary System Disease, pp. 456-457. [2] Kumar V, Abbas AK, et al..

Q: A splenorenal shunt procedure may be required for treatment of:

Bleeding esophageal varices. ***Bleeding esophageal varices*** - A **splenorenal shunt** (Warren shunt) creates an anastomosis between the **splenic vein** and **left renal vein**, effectively decompressing the **portal venous system** and reducing pressure in esophageal varices. - This procedure is specifically indicated for **portal hypertension** with recurrent variceal bleeding that is refractory to medical management and endoscopic interventions. *Mesenteric ischemia* - Mesenteric ischemia results from **inadequate arterial blood supply** to the bowel, typically due to **atherosclerotic disease** or **embolic occlusion** of mesenteric arteries. - Treatment involves **arterial revascularization** procedures like bypass grafting or angioplasty, not portal venous shunting. *Injury to tail of pancreas* - Pancreatic tail injuries are managed with **distal pancreatectomy** with or without splenectomy, depending on the extent of ductal involvement and tissue viability. - This condition requires **direct surgical repair** of the injured pancreatic tissue, not modification of portal venous drainage. *Liver laceration* - Liver lacerations are treated based on hemodynamic stability with **conservative management**, **surgical repair**, or **angiographic embolization** for active bleeding. - Management focuses on **controlling hemorrhage** and preserving hepatic function, not altering portal venous flow patterns.

Q: A 12-year-old patient with esophageal varices is managed by the procedure shown in the image. All of the following statements regarding this condition are true except:

This is the definitive treatment. ***This is the definitive treatment*** - The image shows a **Sengstaken-Blakemore tube** being used, which is a temporary measure for controlling **bleeding esophageal varices**. - It is an emergency treatment used for stabilization and does not address the underlying cause of varices or prevent future bleeding. - **Definitive treatments** include endoscopic variceal ligation (EVL), sclerotherapy, or TIPS procedure. *Sengstaken-Blakemore tube* - The device shown in the image, with balloons and multiple lumens, is indeed a **Sengstaken-Blakemore tube**, used for **tamponade of actively bleeding esophageal varices**. - This tube features a gastric balloon and an esophageal balloon, along with lumens for suction, designed to exert pressure on the bleeding varices. *Gastric balloon is inflated with 400 mL of air* - The **gastric balloon** of a Sengstaken-Blakemore tube is typically inflated with **200-500 mL of air** (often around 250-300 ml in adults, 150 ml in children) to anchor the tube and compress gastric varices. - While 400 mL is within the general range, the exact volume can vary based on patient size and clinical protocol. *Esophageal balloon is inflated with 40 mm Hg pressure of air* - The **esophageal balloon** is indeed inflated to a pressure of **20-45 mmHg (typically 30-45 mmHg)** to compress esophageal varices. - This pressure application is critical for achieving local hemostasis in acute bleeding episodes. *Should be kept inflated for a maximum of 24-48 hours* - The balloons should be deflated after **24-48 hours maximum** to prevent complications such as **esophageal necrosis, ulceration, or perforation**. - Prolonged inflation can cause pressure necrosis of the esophageal or gastric mucosa.

Q: A 29-year-old male who is a doctor by profession, gives a history of prolonged sitting in his OPD hours and presents with discharge and pain. Clinical presentation of the patient is given in the image. What is the most likely diagnosis?

Pilonidal sinus. ***Pilonidal sinus*** - The image shows a **pit** or **opening** in the **natal cleft** with surrounding inflammation and discharge, which is characteristic of a pilonidal sinus. - The history of **prolonged sitting** (*a doctor by profession has prolonged sitting hours in OPD*) and the patient's age (29-year-old male) are common risk factors for pilonidal disease. *Anal fissure* - An anal fissure is a **tear** in the **lining of the anal canal**, typically causing severe pain during and after defecation, and often bright red rectal bleeding. - The lesion in the image is located in the **natal cleft**, not within the anal canal, and presents as a sinus with discharge rather than a linear tear. *Anal fistula* - An anal fistula is an abnormal tunnel connecting the **anal canal to the skin outside** the anus, usually presenting as a small opening with intermittent or persistent discharge of pus or blood. - While it involves discharge, an **anal fistula** typically has an external opening closer to the anus, and the image clearly shows the lesion in the **sacrococcygeal region**, consistent with a pilonidal sinus. *Sentinel pile* - A sentinel pile is a **skin tag** that often accompanies a **chronic anal fissure**, located at the external edge of the fissure. - It is essentially excess skin and usually does not present with **discharge** or the characteristic **sinus tract** seen in the image.
