縱隔胰臟偽囊腫是很少見的胰腺炎併發症。它的綜合症狀和胸部X 光影像很容易地與裂孔性疝氣混淆。在電腦斷層軸向影像,縱隔的胰臟偽囊腫是對醫師臨床診斷的挑戰。我們在此介紹一位51 歲男性以上腹痛,嘔吐和噁心表現。胸部X 光影像和軸向電腦斷層影像顯示後縱隔囊狀病變。此縱隔囊狀病變與裂孔性疝氣影像不易區分。但使用多切面電腦斷層重組影像,就很容易地知道縱隔囊狀病變與胰臟的關係,進而區分裂孔性疝氣。
Mediastinal pancreatic pseudocyst is rarely a complication of pancreatitis. Both the syndrome itself and diagnostic chest radiograph can easily be confused with hiatus hernia. It is a challenge for radiologists to distinguish a mediastinal pancreatic pseudocyst from a mediastinal cystic lesion on CT (computed tomography) axial imaging. Here, we present the case of a 51-year old man with severe epigastralgia, vomiting and nausea. Chest radiograph and axial CT imaging revealed a posterior mediastinal cystic mass which could be mistaken as hiatus hernia. Using MDCT (multidetector computed tomography) coronal and sagittal images, it is easy to distinguish between a mediastinal lesion (e.g., hiatus hernia) and the pancreas, and thus it is possible to distinguish a mediastinal pancreatic pseudocyst.
