Cecal bascule in a patient with complete situs inversus-a rare cause of left upper quadrant abdominal pain.

Cecal volvulus is a rare cause of large bowel obstruction with cecal bascule being a rare cause of cecal volvulus. We present a case of cecal bascule in a 27-year-old female with Kartagener's syndrome and complete situs inversus with no history of prior abdominal surgeries. Computed tomography imaging revealed complete heterotaxia of the intra-abdominal organs with displacement of the cecum to the left upper quadrant with anteromedial rotation concerning for cecal bascule. The patient was taken urgently to the operating room where an upper midline laparotomy was performed. The cecum was found to be edematous with a distinct area of obstruction consistent with radiographic findings and an ileocecectomy was performed. Recognition of rare diagnoses can be rendered even more difficult in a patient with complete situs inversus and requires a high index of suspicion.
