Abstract
We describe an autopsy case of a 61-year-old woman with von Recklinghausen's disease, who died suddenly following intraperitoneal hemorrhage due to the rupture of a giant splenic artery aneurysm. The aneurysm measured 16 x 13 x 5.5 cm--much larger than those in most previous reports. The pancreatic body, which was pressed by the aneurysm, was widely atrophic. In general, splenic artery aneurysms are more frequent in pregnant women or patients with portal hypertension. The pathogenesis of this aneurysm is presumed to be arterial dysplasia, focal arterial inflammation, or portal hypertension, unlike other aneurysms due to arteriosclerosis or syphilis. Since the patient had not been pregnant and had not had liver cirrhosis or arteriosclerosis, the pathogenic factor could not be determined in this case. The relationship between the genesis of the aneurysm and von Recklinghausen's disease was not clear either.
