Cecal bascule in pregnancy: a case report and review of the literature.

A 36-year-old female at 36 weeks' gestation presented with right upper quadrant abdominal pain. She had no prior surgeries. Her pregnancy had been uncomplicated up until her presentation. Abdominal ultrasound was negative for cholecystitis or cholelithiasis, and the appendix was not visualized. During the second day of her hospital course, an abdominal magnetic resonance imaging (MRI) was performed revealing dilated small intestine with air-fluid levels and an inverted-appearing, prominent cecum. She was urgently taken to the operating room for cesarean section followed by abdominal exploration. After delivery of the child, a cecal bascule was found, with a severely distended cecum. To our knowledge, this is the first report of a cecal bascule diagnosed by MRI, and the first diagnosis of cecal bascule in a pregnant patient requiring surgical intervention. We discuss the pathophysiology, diagnosis and treatment of cecal bascule and review the current literature of reported cases.
