【摘要】：目的:探讨卵巢未成熟畸胎瘤的CT表现。方法:回顾性分析21例经手术或病理证实的卵巢未成熟畸胎瘤的病例资料,分析其CT征象。患者年龄5~70岁,中位年龄25岁。17例CA125升高,15例AFP升高,8例CA199升高。结果:21例卵巢未成熟畸胎瘤患者共有23个病灶。CT上病灶以实性为主型14例,囊性为主型6例,混合型1例。瘤体最大径105~290mm,中位最大径175mm。分叶状11例,类圆形10例。边界清晰14例,包膜完整18例,14例伴有腹水。19例平扫呈囊实性混杂密度,实性部分呈片絮状,实性部分内或肿瘤包膜周围散在不规则形、条形、点线状钙化及不规则形、裂隙状、簇状脂肪密度,囊内见多个大小不等小囊腔,壁厚薄不一,增强扫描实性部分及囊壁呈轻度不均匀渐进性强化。2例未见钙化及脂肪密度,主要表现为分叶状、界限清楚、有包膜的低密度肿块,以实性为主,增强扫描呈中度不均匀渐进性强化。结论:卵巢未成熟畸胎瘤CT上呈囊实性,体积较大,边界清楚,有包膜、钙化及脂肪,并伴有腹水,增强呈不均匀强化时有助于本病的诊断。少数卵巢未成熟畸胎瘤无钙化及脂肪。
[Abstract]:Objective: to investigate CT findings of immature teratoma of ovary. Methods: 21 cases of ovarian immature teratoma confirmed by operation or pathology were analyzed retrospectively and their CT findings were analyzed. The age of the patients was 570 years old. The median age was 25 years old. The CA125 increased in 15 cases and the AFP increased in 8 cases. Results there were 23 lesions in 21 cases of ovarian immature teratoma. The lesions on CT were solid type in 14 cases, cystic type in 6 cases and mixed type in 1 case. The maximum diameter of the tumor was 105 mm and 175 mm, respectively. 11 cases were lobulated and 10 cases were round. The boundary was clear in 14 cases, complete capsule in 14 cases, ascites in 14 cases, solid part in 14 cases with cystic and solid mixed density, solid part in sheet flocculation, solid part or around tumor capsule scattered in irregular shape, stripe shape, point linear calcification and irregular shape. Fissures, clusters of fat density, multiple small cavities of different sizes and different thickness of wall were found in the capsule. The enhancement of the solid part and the wall of the capsule showed slight uneven and progressive enhancement without calcification and fat density, mainly in lobular shape. The boundary was clear, the low density mass with capsule was mainly solid, and the enhancement showed moderate uneven and progressive enhancement. Conclusion: the ovarian immature teratoma is cystic and solid on CT, large in volume, clear in boundary, with capsule, calcification and fat, and ascites. The enhancement is helpful for the diagnosis of this disease. A few ovarian immature teratoma have no calcification and fat.
