An Incidentally Found True Portal Vein Aneurysm Secondary to Left Liver Lobe Aplasia in a Non-Cirrhotic Pregnant Woman Presented With Ovarian Torsion

Abstract

We report a rare case of coexistence of true portal vein aneurysm (PVA) with left liver lobe aplasia in a non-cirrhotic pregnant woman presented with ovarian torsion. We discussed the clinical and radiologic findings of a true PVA with left liver lobe aplasia found incidentally in a 27-week pregnant woman presented with acute abdomen and operated for a right side ovarian torsion. Portal vein diameter measured over 20 mm is called as PVA. PVA is an uncommon entity, and most of these aneurysms are acquired and detected in patients with underlying hepatocellular disease and portal hypertension. To the best of our knowledge, there is no report about PVA development secondary to left liver lobe aplasia in English literature. We found this association incidentally in a pregnant woman with normal hepatic parenchyma and no findings of portal hypertension.
