Portal hypertension with intra- and extrasplenic arterial aneurysms and large venous varices.

Imaging studies of two women with portal hypertension demonstrated multiple splenic artery aneurysms, splenomegaly, and large splenic veins varices with a spontaneous splenorenal shunt. In each case, a large splenic hilar, as well as intrasplenic aneurysms were found along with portal vein pressures of about 15 mmHg. Portal hypertension with splenomegaly might be an important factor in the pathogenesis of intra- and extrapaenchymal splenic artery aneurysms.
