Contrast and Radiological Procedures Practice Questions

Q: The barium swallow shows presence of:

Bird beak appearance. ***Bird beak appearance*** - The image shows a **smooth, tapered narrowing of the distal esophagus** with proximal esophageal dilation, a classic sign of **achalasia**. - This appearance resembles a **bird's beak** on a barium swallow study due to the failure of the **lower esophageal sphincter** to relax. *Apple core appearance* - The **apple core sign** is characteristic of an **annular stricture** in the colon, typically caused by a **colonic carcinoma**. - It describes irregular, circumferential narrowing of the bowel lumen with overhanging edges, which is not seen here. *Schatzki's ring* - A **Schatzki's ring** is a benign, circumferential, thin mucosal ring located at the **esophagogastric junction**. - It typically causes intermittent dysphagia for solids but does not present with the diffuse narrowing and significant proximal dilation seen in the image. *Esophageal web* - An **esophageal web** is a thin, eccentric protrusion of mucosa into the esophageal lumen, usually found in the **proximal esophagus**. - It is typically a subtle finding and does not cause the extensive, tapered narrowing and associated proximal dilation observed in this barium swallow.

Q: The following barium swallow study shows which of the following?

Esophageal varices. ***Esophageal varices*** - The Barium Swallow image clearly demonstrates a **serpiginous**, worm-like, or **rosary bead-like appearance** along the esophageal wall, which is characteristic of esophageal varices. - Varices are dilated submucosal veins and appear as **filling defects** on barium studies, especially when distended. *Schatzki ring* - A Schatzki ring is a **thin, symmetric mucosal ring** at the esophagogastric junction, causing solid food dysphagia. - It presents as a **smooth, circumferential narrowing** on a barium swallow, which is not seen here. *Candida esophagitis* - Candida esophagitis typically appears as **ulcerations, plaques, or nodularity** with an irregular, cobblestone pattern on barium swallow. - This image does not show the characteristic **"shaggy" or "cobblestone"** appearance associated with candidal plaques. *Reflux esophagitis* - Reflux esophagitis can manifest as **mucosal irregularity, erosions, or strictures**, but not the distinct serpiginous filling defects seen in this image. - Severe reflux can cause peptic strictures, which appear as **smooth, tapered narrowings**, different from the irregular variceal pattern.

Q: A 45-year-old female patient complains of dysphagia for one year. UGI endoscopy was normal. Diagnosis is: (Recent NEET Pattern 2016-17)

Diffuse esophageal spasm. ***Diffuse esophageal spasm*** - The image shows a **"corkscrew" or "rosary bead" esophagus**, which is a classic radiographic finding in diffuse esophageal spasm due to uncoordinated esophageal contractions. - Dysphagia in this context, coupled with a normal UGI endoscopy (ruling out mechanical obstruction visible by scope), points to a motility disorder. *Zenker's diverticulum* - This is an **outpouching of the pharyngeal mucosa** occurring above the upper esophageal sphincter. - It would typically appear as a distinct barium-filled pouch on a barium swallow, not the diffuse spasm seen in the image. *Dysphagia lusoria* - This is dysphagia caused by **vascular compression of the esophagus**, usually an aberrant right subclavian artery. - It would manifest as a localized external compression rather than the widespread functional spasm shown. *Esophageal carcinoma* - Esophageal carcinoma would typically present as a **fixed filling defect, stricture, or ulceration** on a barium swallow, often with abnormal mucosal patterns. - The UGI endoscopy would likely show an abnormality if carcinoma were present.

Q: A 35-year-old woman presents with progressive dysphagia to solids. A barium swallow study is performed. Which of the following is true regarding the condition shown in the image?

Associated with iron deficiency anemia. ***Associated with iron deficiency anemia*** - The image shows an **esophageal web** in the upper esophagus, characteristic of **Plummer-Vinson syndrome** (also known as **Paterson-Brown-Kelly syndrome**). - This syndrome consists of the classic triad: **iron deficiency anemia**, **dysphagia**, and **esophageal webs**. - The webs are thin membranes of tissue in the upper esophagus that cause intermittent dysphagia to solids. - Treatment involves **iron supplementation** and mechanical dilation of the web if symptomatic. - This is a **premalignant condition** with increased risk of **post-cricoid and upper esophageal squamous cell carcinoma**. *Increased tone of lower esophageal sphincter* - Increased tone of the **lower esophageal sphincter** is characteristic of **achalasia**, which presents with a **"bird's beak" appearance** on barium swallow. - Achalasia is a primary **motility disorder** caused by degeneration of the myenteric plexus, not a structural web. - The image shows a **web in the upper esophagus**, not LES pathology. *Not a premalignant condition* - Esophageal webs, particularly in **Plummer-Vinson syndrome**, are considered a **premalignant condition**. - There is increased risk of developing **squamous cell carcinoma** of the post-cricoid region and upper esophagus. - Regular **endoscopic surveillance** is recommended due to this malignant potential. *It is a normal phenomenon* - The presence of an **esophageal web** is an **abnormal anatomical structure** and pathological finding. - Esophageal webs cause **dysphagia** and are associated with underlying conditions like **iron deficiency anemia**. - Normal esophageal mucosa should be smooth without web-like strictures.

Q: A patient complains of episodes of dysphagia and chest pain. The barium study presentation of the patient is shown below. A radiologist will describe this condition as all except:

Cobble stone appearance. ***Cobble stone appearance*** - **Cobblestone appearance** on barium swallow studies is typically associated with **Crohn's disease** affecting the bowel, characterized by deep ulcerations intersected by edematous mucosa. - This image clearly shows severe, disorganized contractions in the esophagus, which is characteristic of a **motility disorder**, not Crohn's. *Corkscrew appearance* - The image distinctly shows a **twisted, irregular contour** of the esophageal lumen, which is well-described as a **corkscrew esophagus**. - This finding is classic for **diffuse esophageal spasm** (DES), where powerful, uncoordinated contractions occur. *Rosary bead esophagus* - This term is another descriptive phrase for the appearance of the esophagus in **diffuse esophageal spasm**. - The appearance resembles beads on a rosary due to the **simultaneous, non-peristaltic contractions** causing segmental narrowing and outpouching. *Pseudodiverticula* - While not true diverticula which are herniations of all layers, the saccular outpouchings seen between the spastic contractions can be described as **pseudodiverticula**. - These are formed by the irregular, forceful contractions transiently distorting the esophageal wall.

Q: Which of the following is shown in the barium study?

Menetrier's disease. ***Menetrier's disease*** - The barium study shows **markedly thickened gastric folds**, particularly in the fundus and body of the stomach, which is characteristic of Menetrier's disease. - This condition involves **hypertrophy of the gastric mucosa** with associated protein loss, which can be visualized as prominent folds on imaging. *Gastric ulcer* - A gastric ulcer would typically appear as a **focal collection of barium** (crater) that projects beyond the normal gastric lumen, often with surrounding edema. - The image does not show a discrete ulcer crater but rather diffuse thickening of the gastric folds. *Esophageal varices* - Esophageal varices would be seen as **serpiginous filling defects** within the esophagus, particularly in the distal portion. - The image focuses on the stomach and does not display the characteristic features of esophageal varices. *Mallory-Weiss syndrome* - Mallory-Weiss syndrome involves **longitudinal tears in the esophageal mucosa**, usually near the gastroesophageal junction. - These tears are best identified endoscopically and would not typically be visible as diffuse gastric fold thickening on a barium study.

Q: What is the diagnosis based on the barium meal study shown below?

Peptic ulcer disease. ***Peptic ulcer disease*** - The barium meal study shows a distinct **niche** (pocket of barium) within the gastric wall, indicated by the arrow, consistent with an **ulcer crater** - Additionally, there is evidence of **gastric wall edema** and possibly **converging folds** around the ulcer, which are typical radiographic findings in peptic ulcer disease - The smooth, round contour of the niche with radiating folds is characteristic of a **benign gastric ulcer** *Gastric carcinoma* - Gastric carcinoma typically appears as an **irregular, nodular filling defect** with shouldering and abrupt transitions - Malignant ulcers have **irregular margins**, do not show converging folds, and lack the smooth contour seen in this image - The benign features of the ulcer crater here make carcinoma unlikely *Esophageal varices* - Esophageal varices would appear as **serpiginous filling defects** or a "rosary bead" appearance within the esophagus - They are not typically seen in the stomach and do not create a niche or ulcer crater - This image shows findings in the stomach or duodenum, not the esophagus *Hiatal hernia* - Hiatal hernia presents as **herniation of the gastric fundus** through the diaphragmatic hiatus into the thoracic cavity - It appears as a **retrocardiac gas bubble** or mass above the diaphragm on barium studies - No evidence of herniation or diaphragmatic abnormality is seen in this image; the findings are localized to an ulcer crater

Q: A 26-year-old construction worker with a previous history of recurrent kidney stones presents with flank pain. What is the radiological sign demonstrated in the IVP image shown below?

Rim sign. ***Rim sign*** - The image shows a **calcified rim around a radiolucent (non-calcified) center**, which is characteristic of a **calcium oxalate monohydrate stone** on an intravenous pyelogram (IVP). - This sign is also known as the **"lucent-centered calculus"** or **"target sign"** and indicates a partially calcified stone. *Ring sign* - The **ring sign** can refer to various appearances in medical imaging, often indicating a **ring-enhancing lesion** on CT or MRI, which is not applicable to a kidney stone on IVP. - In renal imaging, a ring sign might describe a collection of contrast medium around a tumor or cyst, but not typically a stone with a radiolucent center. *Egg in cup appearance* - This sign is typically associated with **osteochondroma or enchondroma** lesions in bone imaging, where the cartilage cap creates a "cup" for the medullary bone to grow into. - It is not a recognized sign for kidney stones. *Sun burst appearance* - The **sun burst appearance** is characteristic of certain **bone tumors**, particularly **osteosarcoma**, where new bone forms perpendicular to the bone surface. - This description does not apply to the radiological features of kidney stones on IVP.

Q: A 32-year-old lady presents with history of first trimester miscarriage and underwent HSG. The diagnosis is: (Recent NEET Pattern 2018-19)

Unicornuate uterus. ***Unicornuate uterus*** - A **unicornuate uterus** develops from one **Müllerian duct**, resulting in a single functional uterine horn with a characteristic **banana-shaped** or crescent-shaped cavity. - On **HSG**, it appears as a single, elongated cavity that **deviates to one side** and is typically smaller than normal, associated with increased risk of **first trimester miscarriage**. *Bicornuate uterus* - Would show **two distinct uterine horns** separated by a deep fundal cleft, with the uterus appearing **heart-shaped** externally. - HSG would demonstrate **bifurcation** of the uterine cavity into two separate horns at the fundal level with an **intercornual angle >105 degrees**. *Uterus didelphys* - Complete duplication with **two separate uterine bodies**, cervices, and often vaginas resulting from total failure of **Müllerian duct fusion**. - HSG would show **two completely separate uterine cavities** with no communication, not consistent with the single cavity shown. *Arcuate uterus* - Mildest form of **Müllerian anomaly** with only a slight **fundal indentation** and essentially normal uterine cavity size. - HSG shows a **broad, smooth, mild concave contour** of the fundus, not consistent with the elongated, deviated cavity shown.
