Abstract

A 63-year old woman was admitted with severe abdominal pain of 9 hours duration. Past medical history included a polycytemia vera for two years. Laboratory measurements were as follows: white blood cell 47.6×10³/mm³, red blood cell 600×10⁴/mm³, hematocrit 44.0%, hemoglobin 14.2g/dl, platelet 100×10⁴/mm³. Abdominal X-ray CT scan showed a high density ascites. Intraoperatively, 2, 000 ml of intraabdominal haemorrhage and a massive hematoma in the free margin of the omentum were noted. Histological examination of the resected omentum revealed a ruptured mycotic aneurysm.
