    Journal: Clin Imaging; 2017; 44():22-26. PubMed ID: 28407511.
    Abstract:
    PURPOSE: To evaluate clinical and imaging features of pancreatic pseudocyst-portal vein fistula (PPVF). METHODS: Patients with evidence of PPVF on CT/MRI were included. Clinical presentation, outcomes, imaging appearance of the portal vein were recorded. RESULTS: 75% of patients developed portal hypertension, 62% cavernous transformation of the portal vein and 25% portal biliopathy. PPVF presented on CT as fluid-attenuated portal vein, and on MRI as T2-weighted hyperintense fluid-filled portal vein. PPVF was misdiagnosed as portal vein thrombosis in all patients who underwent CT as initial examination. CONCLUSIONS: Whenever PPVF is suspected on CT, MRI can be helpful to achieve accurate diagnosis and avoid unnecessary interventions.
