Internal hernia through the foramen of Winslow: a diagnosis to consider in moderate epigastric pain

Herniation through the foramen of Winslow is a rare condition that can lead to a delayed diagnosis and treatment with a high mortality rate. In most reported cases, patients present to the emergency department with symptoms suggesting intestinal obstruction or with sudden and severe pain in the upper abdomen. Symptoms are non-specific. Clinical diagnosis may be difficult or even missed. The widespread availability of cross-sectional imaging can improve the percentage of correct preoperative diagnosis. We report a case of a caecal and right colic herniation through the foramen of Winslow found incidentally on abdominal computed tomography in a patient presenting with mild epigastric pain.
