Cecal volvulus revealing previously undiagnosed intestinal non-rotation in adulthood: intraoperative diagnosis of a rare congenital anomaly.

Cecal volvulus is a rare cause of acute intestinal obstruction in adults, while intestinal malrotation is typically diagnosed in infancy and only rarely presents in adulthood. We report a rare case of cecal volvulus associated with previously undiagnosed intestinal non-rotation in a 48-year-old patient. The patient presented with acute abdominal pain and was diagnosed with cecal volvulus on computed tomography. Emergency laparotomy confirmed the diagnosis and revealed intestinal non-rotation. The patient was successfully treated with ileocecal resection and primary side-to-side anastomosis. This case highlights the importance of considering congenital rotational anomalies in adult patients presenting with cecal volvulus, as these anatomical variations may predispose to volvulus and may only be recognized intraoperatively.
