【摘要】：目的:探討卵巢未成熟畸胎瘤的CT表現(xiàn)。方法:回顧性分析21例經(jīng)手術(shù)或病理證實(shí)的卵巢未成熟畸胎瘤的病例資料,分析其CT征象�；颊吣挲g5~70歲,中位年齡25歲。17例CA125升高,15例AFP升高,8例CA199升高。結(jié)果:21例卵巢未成熟畸胎瘤患者共有23個(gè)病灶。CT上病灶以實(shí)性為主型14例,囊性為主型6例,混合型1例。瘤體最大徑105~290mm,中位最大徑175mm。分葉狀11例,類圓形10例。邊界清晰14例,包膜完整18例,14例伴有腹水。19例平掃呈囊實(shí)性混雜密度,實(shí)性部分呈片絮狀,實(shí)性部分內(nèi)或腫瘤包膜周圍散在不規(guī)則形、條形、點(diǎn)線狀鈣化及不規(guī)則形、裂隙狀、簇狀脂肪密度,囊內(nèi)見多個(gè)大小不等小囊腔,壁厚薄不一,增強(qiáng)掃描實(shí)性部分及囊壁呈輕度不均勻漸進(jìn)性強(qiáng)化。2例未見鈣化及脂肪密度,主要表現(xiàn)為分葉狀、界限清楚、有包膜的低密度腫塊,以實(shí)性為主,增強(qiáng)掃描呈中度不均勻漸進(jìn)性強(qiáng)化。結(jié)論:卵巢未成熟畸胎瘤CT上呈囊實(shí)性,體積較大,邊界清楚,有包膜、鈣化及脂肪,并伴有腹水,增強(qiáng)呈不均勻強(qiáng)化時(shí)有助于本病的診斷。少數(shù)卵巢未成熟畸胎瘤無鈣化及脂肪。
[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.
