Portal venous aneurysm demonstrated by magnetic resonance imaging

Congenital extrahepatic portal vein aneurysm

Portal vein aneurysm is a rare clinical entity, with only 41 published cases in the English-language literature. Twenty-five of them were congenital. We present the case of a 50-year-old woman who was incidentally diagnosed with a congenital extrahepatic portal vein aneurysm during an investigation for dyspepsia. Ultrasonographic features are described with correlation of computed tomographic and magnetic resonance findings. Etiology, clinical significance, and management strategies for these lesions are discussed and a review of the literature regarding this entity is presented.

Treatment by splenectomy of a portal vein aneurysm in hepatosplenic schistosomiasis

Portal vein aneurysm is a rare medical entity that can be caused by chronic hepatic diseases with portal hypertension. We describe a 45-year-old man with variceal bleeding from hepatosplenic schistosomiasis and an incidentally found intrahepatic aneurysm. Diagnosis was confirmed with non-invasive imaging exams, arteriography and liver biopsy. Following splenectomy, the aneurysm diameter decreased substantially.

[Portal vein aneurysm]

In a 72-year-old female patient suffering from non specific and vague abdominal pain, an aneurysm of the portal vein was discovered. In the absence of complication, and because the risk of operation appeared too high, the decision was to abstain from surgery. With more than 3 years of regular follow-up, the patient was free of symptoms, and the portal vein aneurysm was unchanged. Sixty cases including this one are reviewed.
