Each month, Dr. Maria Flynn issues a Radiology Challenge, presenting images from one of a variety of imaging modalities and a case report. Can you diagnose the condition? Follow the link to find out whether your answer was correct, what was really wrong with the patient, and how the patient was treated. Then, come back next month to test your radiographic reading skills on a new case!

Case report
A 42-year-old woman presented to the emergency department complaining of crampy abdominal pain, nausea, and vomiting that worsened with eating. She reported experiencing similar episodes, which occurred at approximately 6-month intervals over the previous 6 to 7 years. Her surgical history included multiple ventral hernia repairs, a laparoscopic Roux-en-Y gastric bypass (RYGB) in 1996, abdominoplasty, and an abdominal hysterectomy.

Prior medical records were unavailable; however, the patient claimed to have been admitted to the hospital on three occasions for abdominal pain. During one admission, she underwent an exploratory laparotomy, which was significant for a volvulus within an internal hernia.

A physical examination found the patient to be hemodynamically stable. Her abdomen was diffusely tender and distended, with no peritoneal signs. Bowel sounds were hyperactive. Laboratory tests found a white blood cell (WBC) count of 13.1 x 103/µL, and urinalysis findings were noncontributory. Contrast-enhanced computed tomography (CECT) of the abdomen and pelvis was performed (Figures 1-4).
