摘要
目的：探讨不典型卵巢畸胎瘤的CT表现。方法：分析经手术病理证实的CT检查呈不典型表现的卵巢畸胎瘤50例，并与病理结果对照。结果：50例中，均发生于单侧卵巢，右侧27例、左侧23例。大小范围为1．1～12．8am。形状呈类圆形43例、分叶状5例、不规则形2例。囊性或以囊性为主45例、实性5例。根据肿瘤CT表现与病理特征分：囊肿型38例（偏低密度囊肿型12例，高密度囊肿型9例，厚壁囊肿型9例，薄壁囊肿型8例）、无壁全脂肪型3例、实性型5例和混合肿瘤型4例。结论：有些不典型畸胎瘤也具有一定的CT特点，熟悉其CT征象及病理基础有利于提高诊断和鉴别诊断水平。
Objective： To study the CT features of atypical ovarian teratomas. Methods： Collected fifty pathologically proved atypical ovarian teratoma patients, then contrasted the pathological character with the CT manifestation. Results： Only one ovarian were involved in atypical ovarian teratoma in all of the fifty cases, 27 cases in the right ovary, and 23 in the left ovary. The diameter of tumors ranged from 1.1 to 12.8 cm. 43 cases were round shape, 5 were phyllode shape, and 2 were of irregular shape. 45 cases were cystic or solid-cystic, and the remaining 5 were solid lesions. Classified the fifty cases according to CT manifestation and pathological character： 38 cases were cystic form, 3 cases were lipoma form without mural, 5 cases were solid mass form and 4 cases were mixed mass form. 38 cases of cystic form, of which low density were seen in 12 cases, high density in 9 cases, thick mural in 9 cases and thin mural in 8 cases. Conclusions： atypical ovarian teratomas can show some similar CT features which will benefit diagnose and differential diagnose of the disease.
