目的：探讨盆腔良性多囊性病变的CT、MRI影像学特征。方法将38例盆腔良性多囊性病变的CT、MRI表现与病理对照。结果38例患者包括子宫内膜异位症14例，粘液性囊腺瘤4例，浆液性囊腺瘤4例，结核2例，脓肿2例，输卵管积液4例，黄体囊肿伴出血4例，畸胎瘤2例，输卵管妊娠破裂出血1例，淋巴管瘤1例。子宫内膜异位症表现为各囊的囊内CT密度或MRI信号不一，各囊的囊壁厚薄不一；粘液性囊腺瘤呈主囊内见子囊，囊内容物为粘液密度或信号；浆液性囊腺瘤可见乳头状突起或颗粒状钙化；结核性盆腔炎脓腔内见短T2信号提示干酪样坏死和见淋巴结环形强化；盆腔脓肿脓腔内可见气泡影或气液平面；输卵管积液呈扭曲的腊肠样含液体的管状附件结构；黄体囊肿密度及信号随血肿不同时期而改变，伴出血追踪复查可萎缩；输卵管妊娠破裂出血可见孕囊；畸胎瘤可见脂肪和骨组织；淋巴管瘤呈“爬行性生长”。结论通过一些特异性CT、MRI征象分析病变的组织学组成有助于更准确地对盆腔良性多囊性病变进行定性诊断。

Objective To investigate the diagnostic value of CT and MRI in the benign polycystic diseases in pelvis. Methods CT and MR findings of 38 cases were studied in correlation with pathologic results. Results The study population consisted of 14 endometriosis, 4 mucinous cystadennoma, 4 serous cystadennoma, 2 tuberculosis, 2 abscess, 4 hydrosalpinx, 4 corpus luteal cysts, 2 teratomas, 1 tubal pregnancy rupture, 1 lymphangioma. Endometriosis showed different CT density or MRI signal and different wall thickness. Mucinous cystadenoma was seen ascus in the cysts, and content was mucous density or signal. Serous cystadenoma showed papillary projection or granular calcification. The pus cavity was short signal in T2WI and lymph node ring enhancement in pelvic tuberculosis. Bubble and gas-liquid plane could be seen in pelvic abscess. Hydrosalpinx was shown distorted fluid containing tubular structures. The density and signal of corpus luteum cyst were changed with hematoma in different periods and change, and may atrophy. There were fat and bone tissue in teratomas. There was gestational sac in tubal pregnancy rupture. Lymphangioma was a"creeping growth". Conclusion Familiarity with the CT and MR imaging features of their histologic components, couple with knowledge of specific signs, were helpful for more accurate diagnosis.
