Point of care ultrasound of his abdomen showed a large fluid filled structure with well-defined borders containing gastric contents extending from the xiphoid process to the umbilical region. No free fluid was noted on focus assessment with sonography for trauma (FAST) examination. A computed tomography (CT) scan was performed emergently and it was noted that the patient had a significantly distended stomach and gastric volvulus (blue arrows) noted in the area of his paraesophageal/hiatal hernia.

Computed tomography of the abdomen and pelvis with contrast show edema of the pancreas (red outline) and duodenum (yellow arrow) with peripancreatic inflammation, fluid and fat stranding (blue highlight). The distal pancreatic tail was noted to appear normal (green arrow). There was no organized drainable fluid collection, and no parenchymal hypo-enhancement. These findings are consistent with moderate severity acute interstitial pancreatitis.

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.

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).
