Ruptured hepatic artery aneurysm: an unusual presentation of polyarteritis nodosa.

A 52-year-old woman presented with severe acute right upper quadrant abdominal pain and signs of intra-abdominal haemorrhage. CT and selective angiography revealed a ruptured right hepatic artery aneurysm and diffuse aneurysmatic disease involving most intra-abdominal organs, suggestive of polyarteritis nodosa. Although treatment with high-dose steroids was initiated, the patient died of progressive bowel ischaemia.
