Portal vein aneurysm, an update on the subject. A case report.

The portal venous aneurysm(PVA) is a very rare entity, which can be congenital or acquired (if portal hypertension, cirrhosis, pancreatitis, surgical history). Although the discussion is still ongoing, treatment would be indicated in symptomatic PVA, over 30mm or progressive growth. In order to provide an update on the subject due to the low incidence of this finding, we present the case of a 51-year-old woman who comes to the ER for painful obstructive jaundice; the ultrasound shows the presence of cholelitiasis and choledicolitiasis and identifies a nodular image in continuity with the right portal branch of 25x22x21 mm. This dilation is confirmed by MRI. After committee evaluation, follow-up was decided and to reserve the possibility of embolization if growth or symptomatology appeared.
