Retroperitoneal benign cystic teratoma is relatively rare in adults. We report a case of traumatic rupture of primary retroperitoneal teratoma into peritoneum that produced chemical peritonitis. It was demonstrated by computed tomography, which showed fat-fluid levels in the peritoneum. We suggest that the demonstration of fat-fluid levels in the peritoneum could be a reliable sign of intraperitoneal rupture of abdominal teratoma and subsequent chemical peritonitis.
成人腹膜后良性囊性畸胎瘤相对少见。我们报告一例原发性腹膜后畸胎瘤外伤性破裂进入腹腔导致化学性腹膜炎的病例。计算机断层扫描显示腹腔内有脂肪-液平面，证实了这一情况。我们认为腹腔内出现脂肪-液平面可能是腹部畸胎瘤腹腔内破裂及继发化学性腹膜炎的可靠征象。
