Summary

A 37-year-old woman presented with a 3-hour history of back pain, nausea and vomiting and an episode of syncope. A fluid collection in the lesser sac was detected on ultrasound and CT scan. Emergency laparoscopy and subsequent laparotomy were performed and a large blood clot was evacuated from the lesser sac. No identifiable source or predisposition to bleeding was found. She made a full recovery postoperatively. There are few reported cases of spontaneous intraperitoneal haemorrhage. In a third of cases, there is no identifiable source of bleeding. Unfortunately, patients present late with non-specific symptoms and a prompt diagnosis is difficult to make. The case reiterates the importance of awareness of lesser sac haematoma formation; an unusual clinical entity with a high morbidity and mortality rate. A high index of suspicion, radiological adjuncts and appropriate surgical intervention, especially in unstable patients, is essential for a good outcome.
