摘要

後腹膜腔畸胎瘤是少見的腫瘤，本文報告一個三十一歲男性患有後腹膜腔畸胎瘤，有巨大腹部腫塊表徵。臨床上，在患者腹部左上方可摸到一個沒有疼痛的巨大腫塊。手術前腹部放射線檢查可發現類似牙齒的鈣化組織，加上腹部電腦斷層攝影檢查，手術前診斷為畸胎瘤。手術時發現上腸系膜動脈與腫瘤包囊緊緊黏連，因此只能部份切除腫瘤包囊，拿掉包囊內容物，發現有三公升黃色液體、牙齒、頭髮、脂肪等等，腫瘤根源自後腹膜腔，最後把腫瘤包囊縫合。手術後患者恢復良好，四個月門診追蹤發現患者生理狀況良好，沒有腫瘤復發現象。因此病例少見，故特提出報告。

A case of retroperitoneal teratoma in a 31-year-old male is presented. Clinically, a huge nontender mass over the left upper quadrant of the abdomen without nausea and vomiting was noted. Amorphous calcification and calcified teeth were found on the plain abdominal film. A diagnosis of retroperitoneal teratoma was made preoperatively by roentgenography and computed tomography (CT) of the abdomen. This huge tumor originated in the retroperitoneal space and displaced the contents of the entire abdominal cavity. Because the pseudocapsule of the tumor incorporated the superior mesentery artery, surgical treatment consisted of evacuation of the cyst, sponging out the contents and leaving the empty cyst. The case report is interesting not only for the tumor size, but also for the rarity of its existence in the fourth decade of life.
