摘　　要：目的　进一步提高卵巢肿瘤的 CT诊断准确性。方法　对经临床证实的 6 5例良恶性卵巢肿瘤的 CT表现进行回顾性分析。结果　良性囊腺瘤 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 CT表现囊内有脂肪 ,壁结节处有钙化或碎片。囊性恶性肿瘤的特征是肿瘤壁和分隔厚且不规则 ,肿瘤内软组织成分较多。结论　CT是诊断卵巢肿瘤的一种有效的检查方法 ,正确认识各种卵巢肿瘤的Objective To improve diagnostic accuracy of ovarian tumors on computed tomography(CT).Methods CT scans of 65 patients with surgical proof of various ovarian tumors were retrospectively evaluated.Results Benign serous and mucinous cystadenomas were characterized by CT as thin walled cystic lesions without evidence of soft tissue components, irregular wall, or papillary projections. Cystic teratomas could be reliably diagnosed by CT by their fatty density and often a mural nodual, which contained calcifications, hair or solid structures. Characteristics of cystic malignant tumors were as follows: the wall and septa of tumors were thick and irregular, a papillary projection or irregular solid component in cystic tumors could be seen.Conclusion CT is one of the best methods for diagnosis of ovarian tumor, and CT is helpful in increasing the accuracy rate of diagnosis.
