False aneurysm of the superior mesenteric artery--a complication of pancreatitis.

Early recognition of pseudocyst formation in pancreatitis has been a very important contribution of diagnostic ultrasound. Furthermore, haemorrhage or abscess formation, an additional complication, can also be suspected by this diagnostic modality. False aneurysm formation of a larger, neighbouring artery is not easily recognized by ultrasound. It is for this reason that this case report is made.
