卵巢囊肿性病变的CT诊断及鉴别诊断

目的进一步提高卵巢囊肿性病变的ＣＴ诊断准确性。方法对经临床证实的６０例各种卵巢囊肿性病变进行回顾性分析。结果卵巢囊肿（１４例）的特征为薄壁的囊性肿块，且囊壁较规则。良性囊腺瘤（２７例）ＣＴ的特征表现为薄壁、没有明显的软组织成分，或有乳头状凸出。畸胎瘤（３例）ＣＴ表现囊内有脂肪，壁结节处有钙化或碎片。恶性肿瘤（１６例）的特征是肿瘤壁和分隔厚且不规则，肿瘤内软组织万分较多。结论ＣＴ对于卵巢囊肿性病变是

CT diagnosis and differentiation of ovarian cystic diseases

Purpose To improve diagnostic accuracy of ovarian cyst diseases on computed tomography ( CT) . Methods CT scans in 60 patients with surgical confirmed various ovarian cystic diseases were retrospectively studied. Results Ovarian cysts (14 cases) are characterized by thin - wall cystic mass, cystic wall are regular. Benign serous and mucinous cystadenomas (27 cases) are characterized by CT as thin- wall cystic lesions without evidence of soft tissue components, irregular wall, or papillary projections. Cystic teratomas (3 cases) can be reliably diagnosed by CT by their fatty density and often a mural nodule, which contains calcifications hair and solid structures. Characteristics of cystic maglignant tumors (16 cases) are as follows; the wall and septa of tumors are thick and irregular, a papillary protrusion or irregular solid component in cystic tumors can be seen. Conclusion CT is one of the best methods for diagnosis of ovarian cystic diseases, and CT is helpful in improving the accuracy rate of diagno-
