A 43-year-old woman complaining of upper abdominal pain was referred to our clinic. Well movable mass was detected in the right hypochondria region by palpation. Three years before, she underwent cholecystectomy and choledochotomy for cholelithiasis. After that she had been aware of painless mass in the right hypochondria region, but because of no symptom she regarded it as operative scar and had no treatment. Abdominal CT, ultrasonography, upper GI series and barium enema revealed a retroperitoneal cyst compressing the 3rd portion of the duodenum upward and the vena cava backward. Laparotomy showed an unilocular chylous cyst, 5 cm in diameter in the retroperitoneal cavity. Histologically, the cyst was cystic lymphangioma. Etiologically, the previous operation of cholecystocholedocholithiasis was supposed to be a trigger of the development of the chylous cyst.
一位43岁主诉上腹部疼痛的女性被转诊至我院。触诊发现右季肋区有一可活动的肿块。三年前，她因胆结石接受了胆囊切除术和胆总管切开术。此后，她意识到右季肋区有无痛性肿块，但由于没有症状，她认为是手术瘢痕，未接受治疗。腹部CT、超声、上消化道造影和钡剂灌肠显示一个腹膜后囊肿，向上压迫十二指肠第三段，向后压迫腔静脉。剖腹探查显示腹膜后腔有一个直径5厘米的单房乳糜囊肿。组织学检查显示该囊肿为囊性淋巴管瘤。从病因学角度来看，之前的胆囊胆总管结石手术被认为是乳糜囊肿形成的诱因。
