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.
目的
评估胰腺假性囊肿-门静脉瘘（PPVF）的临床及影像学特征。
方法
纳入CT/MRI检查显示有PPVF证据的患者。记录临床表现、预后及门静脉的影像学表现。
结果
75%的患者出现门静脉高压，62%的患者出现门静脉海绵样变性，25%的患者出现门静脉性肝病。PPVF在CT上表现为门静脉内液体衰减，在MRI上表现为T2加权像上高信号的充满液体的门静脉。所有以CT作为初始检查的患者中，PPVF均被误诊为门静脉血栓形成。
结论
当CT上怀疑有PPVF时，MRI有助于准确诊断并避免不必要的干预。
