| Summary: | Portal vein aneurysm (PVA) is a rare vascular entity. Here, we describe cases of 2 separate patients who presented with congenital and acquired causes of PVA respectively. The first patient presented with vague abdominal pain and was incidentally diagnosed with PVA, whereas the cause in the second patient was iatrogenic. With a limited number of cases published to date, there is little data on the natural history of the disease. Herein, we will discuss the radiological findings aiding us in reaching our diagnosis and also the probable mimickers of the disease, with a brief overview of its possible causes, complications, and the currently available management options.
