On the coronal sections of computed tomography (CT), bilateral renal infarctions (blue arrows) and several splenic infarctions (green arrows) are noted. Of particular interest, part of the clot totally occluding the left renal artery visibly extends into the aorta (red arrow). The vascular reconstruction image is remarkable for the absent left kidney, the unusual contour of the right kidney and the abnormal splenic blush.

A CT scan of his abdomen/pelvis shows acute sigmoid colonic diverticulitis with adjacent extraluminal collection containing gas (axial view, white arrow) consistent with perforation, along with abutment of the urinary bladder with intraluminal bladder gas (sagittal and coronal views, white arrowheads) suggesting colovesical fistula.

The patient’s abdominal ultrasound revealed intussusception in the right upper abdominal quadrant. The transverse ultrasound view showed a “doughnut sign” (dashed yellow line), telescoping bowel (yellow arrow), and invaginated hyperechoic mesenteric fat with crescent configuration (dashed orange line). The sagittal ultrasound view demonstrated the intussusception formed by the outer recipient bowel loop (yellow arrows), invaginated hyperechoic mesenteric fat (orange asterisks), and telescoping bowel centrally (red arrow).

By the end of this instructional session learners should be able to: 1) Discuss the indications, contraindications, and complications associated with abdominal paracentesis; and 2) competently perform an ultrasound-guided abdominal paracentesis on a simulator and remove fluid.

Recurrent Sigmoid Volvulus in a Young Female

DOI: https://doi.org/10.21980/J8GW5SIssue 3:3 No ratings yet.

Computed tomography (CT) of the abdomen and pelvis was obtained revealing a colonic volvulus in the left mid to upper abdomen (blue arrow) involving the distal transverse colon and descending colon, with gaseous colonic distention to 8.5 cm (red arrow). The characteristic “whirl pattern” is also present (yellow arrow). These findings are suggestive of a high-grade colonic obstruction. It was without evidence of pneumoperitoneum, pneumatosis, or drainable collection. Of note, a 3.6 cm dermoid tumor is also observable in the left adnexa (green arrow).

After an unremarkable chest radiograph was obtained, a computed tomography (CT) scan of the chest was obtained due to possible co-ingestion of bones to rule out perforation. The CT scan demonstrated focal distention of the mid-esophagus due to an impacted food bolus (white arrow). An aberrant right subclavian artery (yellow arrow) was located just distal to the impaction site with partial compression of the esophagus (red arrow).

The two-view chest X-ray shows mild opacification of the bilateral lower lobes concerning for pneumonia (red arrows). Incidental retrocardiac opacity with air-fluid level consistent with large hiatal hernia is also observed (green arrow).

Button Battery in Esophagus

Chest radiograph showed the presence of a round radiopaque foreign body in the mid-chest. It was suspected to be in the esophagus rather than in the trachea due to the en-face positioning of the foreign body. The foreign body demonstrated two concentric ring circles concerning for a “double ring” or “halo" sign, which was suggestive of the presence of a button battery rather than a coin.

Achalasia: An Uncommon Presentation with Classic Imaging

The chest X-ray demonstrated a markedly widened mediastinum (red brackets), raising concern for thoracic aortic aneurysm/aortic dissection, which prompted labs and contrast-enhanced computed tomography (CT) of the chest. The CT revealed a dilated proximal esophagus that narrowed distally (yellow tracing and red arrow), with particulate material, mass-effect on the trachea (purple outline), and bilateral patchy opacities suggesting aspiration. Barium esophagram showed a drastically dilated esophagus filled with contrast (yellow arrow), terminating into the classic “bird’s beak sign” (red arrow) at the lower esophageal sphincter (LES). Esophageal manometry later confirmed achalasia, proving that widened mediastina can have unexpected etiologies.
