【摘要】：目的:探讨几种卵巢原发少见肿瘤的CT特点,提高对该类病变的认识。方法:分析经病理证实的16例卵巢少见肿瘤的临床及CT资料,观察瘤体的大小、形态、包膜、密度及强化特点,并结合病理结果分析卵巢少见肿瘤的CT特点。结果:硬化性间质瘤3例,肿瘤呈椭圆形,均为囊实性,有包膜,密度不均匀;增强后呈现"海绵状血管瘤"样强化;孤立性纤维瘤2例,呈囊实性,均有包膜,密度不均匀,增强后明显不均匀强化,动脉期周边可见多支供血动脉显影;卵巢甲状腺肿6例,呈椭圆形,实性3例,囊实性3例,均有包膜,密度不均匀,5例内伴不定形钙化,4例含有脂肪,增强扫描实质部分明显强化;Bernner瘤5例,呈圆形或椭圆形,实性4例,囊实性1例,均有包膜,密度不均匀,3例伴不定形钙化,增强后轻度不均匀强化。结论:通过分析卵巢少见肿瘤的大小、形态、包膜、密度及强化特点,对肿瘤的定性诊断及鉴别诊断有一定的价值。
[Abstract]:Objective: to investigate the CT features of several rare primary ovarian tumors and to improve their understanding. Methods: the clinical and CT data of 16 cases of rare ovarian tumors proved by pathology were analyzed, and the size, shape and capsule of the tumor were observed. Ct features of rare ovarian tumors were analyzed in combination with the characteristics of density and enhancement. Results: sclerosing stromal tumors in 3 cases were oval, all of them were cystic and solid, had capsule, and the density was uneven. After enhancement, "cavernous hemangioma" was observed in 2 cases of solitary fibroma, all of them had capsule, density was uneven, enhancement was not even, and multiple blood supply arteries could be seen around the arterial phase. 6 cases of ovarian goiter were oval-shaped, 3 cases solid, 3 cases of cystic solid, all cases had capsule, 4 cases had fat in 5 cases with irregular calcification, 5 cases had enhanced Bernner's tumor on enhancement scanning, which were round or elliptical. There were 4 cases of solid, 1 case of cystic solid, 3 cases of heterogeneous density with amorphous calcification, and slight heterogeneous enhancement after enhancement. Conclusion: the size, morphology, capsule, density and enhancement characteristics of rare ovarian tumors were analyzed. It has certain value for qualitative diagnosis and differential diagnosis of tumor.
