Abstract

Pancreatic pseudocyst rupture into the portal vein is a very rare complication and only three reported cases were confirmed using MRI. We report the case of a 50-year-old man with fistula formation between the pseudocyst and the portal vein, confirmed noninvasively by MRI. T2-weighted MR images and magnetic resonance cholangiopancreatography showed fluid signal intensity within the portal, superior mesenteric, and splenic veins, and a direct communication between the pseudocyst and the portal vein.

간문맥으로 파열된 췌장 가성낭종은 매우 드문 합병증이며, 자기공명영상으로 확진된 경우는 3예만 보고되어 있다. 저자들은 50세 남자 환자에서 가성낭종과 간문맥 사이에 형성된 누공을 자기공명영상을 이용하여 비침습적으로 확진한 증례를 보고한다. T2강조영상 및 자기공명 담체관조영술에서 간문맥, 상장간막정맥, 그리고 비장정맥 내에 액체신호가 보였으며, 가성낭종과 간문맥이 직접 연결된 소견을 보였다.
