Aneurysms of the portal venous system: ultrasonography and CT findings.

Objective: The retrospective study of aneurysms of the portal venous system and their possible aetiology, using different imaging methods.

Material And Methods: Between 1992 and 1995 we collected 13 cases of portal vein aneurysm from 11 patients, eight of whom suffered portal hypertension (PH) secondary to hepatic cirrhosis. All were diagnosed by means of ultrasonography (155) and/or computed tomography (CT).

Calcification of lumbar ligamentum flavum and facet joints capsule.

Study Design: The incidence of calcification in ligamentum flavum and posterior capsule demonstrated by computed tomography was reviewed in a series of 147 patients in whom 419 lumbar levels were studied.

Objectives: To find a relationship between mechanical lumbar pathology and the calcification of the ligamentum flavum and posterior capsule.

Summary Of Background Data: Calcification of the ligamentum flavum and posterior capsule has been found in diffuse idiopathic skeletal hyperostosis and in metabolic disorders.
