An intramesosigmoid hernia is 1 of the 3 rare types of sigmoid-related hernias that could be complicated by intestinal obstruction. Our patient presented with a clinical picture of intestinal obstruction. CT scan showed features of strangulated small-bowel obstruction secondary to a sigmoid-related hernia. This was confirmed intraoperatively to be an intramesosigmoid hernia. We share the radiological findings with intraoperative surgical correlation and discuss the imaging features described in the literature.

BACKGROUND Internal hernias involve protrusion of the small bowel through a peritoneal or mesenteric space in the abdominal or pelvic cavity. Congenital internal small bowel hernias are rare and patients with them usually present with small bowel obstruction (SBO) at a young age, whereas in older patients, internal small bowel hernias usually are acquired secondary to previous surgery. The present report is of a rare case of SBO due to dual congenital internal small bowel hernias in a 51-year-old man with no history of abdominal surgery.

An internal hernia is defined as a protrusion of an abdominal viscera through the defects of the gastrointestinal mesentery or peritoneum-lined fossa. Sigmoid mesocolic hernias are an uncommon type of internal hernias, accounting for only 6% of all internal hernias. Furthermore, intramesosigmoid hernia is one of the three subtypes of the sigmoid mesocolic hernias.

Intramesosigmoid hernias are a rare cause of small bowel obstruction. Here, we present such a case with learning points derived from diagnostic dilemma, shared decision making in consent and the management of a rare cause of a common surgical emergency.

Background: Internal hernia is a rare cause of intestinal obstruction, and sigmoid mesocolon hernia is an extremely rare form of this condition. Among sigmoid mesocolon hernias, intramesosigmoid hernia is the least frequent subtype. We described a case of intramesosigmoid hernia through the orifice on the right leaf of the mesosigmoid with an incarcerated ileum of 6 cm in length without strangulation.
