目的 :探讨腹部巨大囊性病变的CT诊断和鉴别诊断要点。方法 :腹部巨大囊性病变 3 0例 ,均经手术病理证实 ,分析其病变中心点、边界、囊壁、分隔、钙化、液平征、强化等要素。结果 :中下腹包块 14例 ,有 15个包块。其中 :卵巢浆液性囊腺瘤 4例 ,5个包块。粘液性囊腺瘤 3例 ,卵巢囊肿 1例 ,卵巢—输卵管炎性囊肿 1例 ,巨大膀胱憩室 1例 ,成熟性囊性畸胎瘤 4例 ;中上腹包块 13例 ,其中 :囊性淋巴管瘤 5例 ,肠重复畸形囊肿 2例 ,小网膜囊内神经鞘瘤囊性变 1例 ,胆总管囊肿 3例 ,非胰腺性假性囊肿 2例 ;腹膜后包块 3例 ,有胰腺假性囊肿 1例 ,重度肾积水 2例。结论 :腹部巨大囊性病变绝大多数为良性 ;包块中心点位于中下腹者以女性附件疾患发病率最高 ;囊性淋巴管瘤在腹部囊性病变中占有一定比例 ,并且腹膜后发病也不少见。
Objective: To investigate the diagnosis and differential diagnosis of giant cystic lesions in the abdomen. Methods: Thirty patients with giant cystic lesions in the abdomen were confirmed by surgery and pathology. The center, boundary, wall, septum, calcification, fluid level and enhancement were analyzed. Results: In the lower abdomen mass in 14 cases, there are 15 mass. Of which: ovarian serous cystadenoma in 4 cases, 5 mass. 3 cases of mucinous cystadenoma, 1 case of ovarian cyst, 1 case of ovarian-tubal inflammatory cyst, 1 case of giant bladder diverticulum, 4 cases of mature cystic teratoma; 13 cases of middle and upper abdominal mass, of which cystic 5 cases of lymphangioma, 2 cases of intestinal deformity cyst, 1 case of cystic degeneration of schwannoma in cyst, 3 cases of choledochal cyst, 2 cases of non-pancreatic pseudocyst, 3 cases of retroperitoneal mass 1 case of pancreatic pseudocyst, 2 cases of severe hydronephrosis. Conclusion: Most of the giant cystic lesions in the abdomen are benign; the center of the mass is located in the middle and lower abdomen with the highest prevalence of the disease; the cystic lymphangioma accounts for a certain proportion in the cystic lesions of the abdomen, and the incidence of retroperitoneal disease is not Rare.
