目的：提高对卵巢肿瘤ＣＴ表现的认识及诊断。方法：详细分析了４２例经病理证实的卵巢肿瘤的ＣＴ表现。结果：（１）非赘生性囊肿和囊腺瘤的特征为薄壁的囊性肿物，壁与间隔薄且规则。ＣＴ可识别囊内新近出血。（２）肿物内含脂肪成份，囊壁隆起的实性结节处见结节状钙化或牙齿是囊性畸胎瘤定性诊断的特征性表现。（３）恶性囊性肿瘤的特征为囊壁与间隔不规则增厚，其内可发现乳头状或不规则实性成份。结论：ＣＴ是诊断本病的重要的影像学检查手段。结合临床综合分析，有助于提高诊断准确性。
Objective: To improve the understanding and diagnosis of CT findings of ovarian tumors. Methods: The CT findings of 42 pathologically confirmed ovarian tumors were analyzed in detail. Results: (1) Non-neoplastic cysts and cystadenomas are characterized by thin-walled cystic masses with thin and regular walls and spaces. CT can recognize intracapsular hemorrhage. (2) the tumor contains fatty components, solid nodules protruding at the cystic wall see nodular calcification or teeth is a characteristic manifestation of qualitative diagnosis of cystic teratoma. (3) malignant cystic tumor characterized by irregular wall and interval thickening, which can be found in papillary or irregular solid composition. Conclusion: CT is an important imaging method for diagnosis of this disease. Combined with clinical analysis, help to improve the diagnostic accuracy.
