摘　　要：目的探讨卵巢透明细胞癌（OCCA）的CT和MRI表现。方法回顾性分析9例经病理证实的OCCA的CT及MRI资料。对6例行CT平扫及增强检查，对7例行MR平扫及增强扫描。结果9例中，4例先后接受CT及MR平扫、增强检查，2例仅接受CT平扫及增强检查，3例仅接受MR平扫及增强检查。①肿瘤位于左侧卵巢3例，右侧4例，跨中线生长2例，瘤体直径2．2～12．4cm；8例为囊实性肿块，以囊性为主，1例为多房囊性肿块。②CT表现：6例中，5例为以囊性为主的囊实性肿块，均为单房，密度均匀，1例为多房囊性肿块，囊液密度不均，囊内分隔粗细均匀；动脉期5例实性部分及分隔中度强化，1例明显强化；静脉期均持续强化。6例均见完整包膜，延迟强化呈稍高密度。⑧MRI表现：7例中，6例为以囊性为主的囊实性肿块，囊性部分呈长T1长T2信号，实性部分呈稍长T1稍长T2信号，DW1均呈高信号；1例多房囊性肿块，囊液信号不均，分隔呈等T1稍长T2信号。增强扫描6例肿瘤实性部分动脉期不均匀强化，静脉期均呈持续性较均匀明显强化，分隔持续明显强化。延迟期包膜持续强化，呈稍高信号。结论OCCA的CT和MRI表现具有一定特征，有助于与其他富血供肿瘤相鉴别。Objective To investigate CT and MRI manifestations of ovarian clear cell adenocarcinoma （OCCA）. Methods CT and MRI findings of 9 patients with OCCA proved with pathology were analyzed retrospectively. Plain and contrast- enhanced CT were performed in 6 patients, while plain and contrast-enhanced CT were performed in 7 patients. Results Among 9 patients, 4 underwent both CT and MRI, 2 underwent single CT, while 3 underwent single MR examination. @ The tumors located in the left in 3 patients, located in the right in 4 patients, and cross the center line in 2 patients. Tumor diameters were 2.2--12.4 cm. Tumors in 8 patients were cystic-based solid and cystic masses, and in 1 patient was multi- locular cystic mass. （2）CT manifestations： Unilocular cystic-based solid and cystic masses were found in 5 patients, and the fluid density of cysts were uniform, while intracapsular separate thickness was uniform in a multilocular cystic mass in 1 patient, and the density of cyst fluid was uneven. Solid ingredients and separated moderately enhanced in 5 cases, while significantly enhanced in 1 case at arterial phase, all continued strengthen at venous phase. Complete capsule was seen in all 6 cases, and slightly delayed enhancement showed higher density was noticed. Q MRI manifestations： For cystic-~based sol- id and cystic mass in 6 patients, the cystic part showed more uniform long Ti and long T2 signal, the solid Component showed slightly long T1 and long T2 signal, DWI showed high signal. For 1 patient of muhilocular cystic mass, cyst fluid signal was uneven and capsule separate showed equal T1 and slightly long T2 signal. The solid ingredients of 6 cases heter- ogeneously enhanced at arterial phase, enhanced persistently and significantly at venous phase. All the capsule of masses sustained strengthen and showed slightly higher signal at delay period. Conclusion CT and MRI findings of OCCA have certain characteristics, being helpful to differential diagnosis of OCCA from other tumors with rich blood supply.
