“…According to these results, clearance of HCV by DAA treatment not only regressed liver fibrosis but may have also restrained the progression of PVA. Six PVA cases with persistent HCV infection were reported previously; however, there were no cases who received antiviral treatment [8, 10‒14]. As far as we know, this is the first report of PVA in a patient with cirrhosis type C treated with antiviral therapy.…”

Introduction: Portal vein aneurysm (PVA) is a rare saccular or fusiform portal vein dilatation. The management and optimal treatment of PVA remain unknown. Case Presentation: A 53-year-old man with hepatitis C virus (HCV) infection was diagnosed with PVA measuring 28 mm in diameter. Under observation, his liver fibrosis progressed, and the PVA diameter gradually increased to 52 mm. The patient was treated with elbasvir-grazoprevir for 12 weeks, and HCV disappeared. After achieving sustained virological response, liver fibrosis improved and the PVA progression ceased. Conclusion: HCV clearance by direct-acting antiviral treatment not only regressed liver fibrosis but may have also restrained the progression of PVA in a patient with cirrhosis type C and PVA.

“…Increased use of abdominal cross-sectional imaging in recent years has led to a growing number of cases describing PVA, and as such, proper handling of this lesion is increasingly relevant to both diagnostic and interventional radiologists. Evaluation of PVA by multiple imaging modalities is important because a PVA can mimic solid, cystic or hypervascular abdominal masses[ 1 - 7 ].…”

“…A portal vein aneurysm (PVA) is the abnormal focal saccular or fusiform dilatation of the portal venous system, and it is defined as a PV diameter exceeding 19 mm in cirrhotic patients and 15 mm in a normal liver. It is a rare vascular abnormality, representing 3% of all venous aneurysms in the human body, and is not well understood[ 1 - 7 ].…”

“…Aiming to clarify novelty as regards this visceral vascular abnormality, we performed a literature search of the PubMed database for all articles relating to PVA between January 2015 and July 2022[ 12 - 68 ]. We collected 57 reports, involving 62 patients with a PVA[ 3 - 7 , 12 - 16 , 19 , 21 - 25 , 27 , 29 - 68 ]; we also found one retrospective study with 18 PVA patients[ 2 ], and three cases of PV pseudoaneurysm[ 69 - 71 ].…”

Portal vein aneurysm (PVA) is a rare vascular abnormality, representing 3% of all venous aneurysms in the human body, and is not well understood. It can be congenital or acquired, located mainly at the level of confluence, main trunk, branches and bifurcation. A PVA as an abnormality of the portal venous system was first reported in 1956 by Barzilai and Kleckner. A review from 2015 entitled “Portal vein aneurysm: What to know” considered fewer than 200 cases. In the last seven years, there has been an increase in the number of PVAs diagnosed thanks to routine abdominal imaging. The aim of this review is to provide a comprehensive update of PVA, including aetiology, epidemiology, and clinical assessment, along with an evaluation of advanced multimodal imaging features of aneurysm and management approaches.
