Internal hernias are rare, occurring in 0.2–0.9% of autopsy cases. Hernias through the foramen of Winslow are even rarer, occurring in up to 8% of internal hernias. The clinical presentation is variable, making diagnosis difficult, and a delay in diagnosis can result in significant morbidity. As such, early radiological diagnosis is paramount. We report a rare case of caecal herniation through the foramen of Winslow in a 49-year-old female patient in whom the diagnosis was made radiologically and allowed appropriate and prompt management.
