Until recently aneurysms in the portal venous system were considered to be
very rare lesions. This opinion has largely been changed by the increasing
number of cases reported in recent years. In this paper we report the cases
of five patients with portal venous system aneurysms, including one with
splenic vein aneurysm. One patient had associated portal hypertension. The
reexamination of two patients 2 years later showed no change in the
aneurysms. The sonographic features and related literature are reviewed. In
the light of this series and the information in the literature, we
recommend that portal venous system aneurysms should no longer be
considered exceptionally rare entities.
