16排螺旋CT对卵巢浆液性肿瘤的诊断价值

Value of 16 Slice Spiral CT in Diagnosis of Ovarian Serous Tumor

目的:通过对卵巢浆液性肿瘤CT表现分析,探讨16排螺旋CT对其诊断的价值。材料与方法:回顾分析28例经手术及病理证实的卵巢浆液性肿瘤的影像特征,其中良性浆液性肿瘤13例,交界性3例,恶性肿瘤12例,全部经CT平扫和增强扫描,并重建动脉期MPR。结果:良性病灶以单房囊为主,囊壁小结节2例,11例出现分隔,6例呈现多房状,囊壁、分隔及小结节出现轻度强化。恶性肿瘤呈囊实性,边界不清,内部密度不均匀,分隔厚薄不均匀,可见大小不等壁结节,早期增强后囊壁及壁结节明显强化,2例伴随腹水。2例囊壁稍厚,未见明确壁结节,病理证实为浆液性囊腺癌。结论:浆液性囊腺瘤多见于单囊且囊壁强化不明显;浆液性囊腺癌以混杂的囊实性为主,具有较明显的早期强化表现;运用16排CT扫描有助于判断卵巢浆液性肿瘤的性质。

Purpose： Through analyzing the CT manifestations of ovarian serous tumor, investigate 16 SCT diagnostic value on it. Materials and Methods： Image manifestations of 28 cases of proved by surgery and pathology were analyzed ret- rospectively, Including 13 cases of benign serous tumors, border sex 3 cases, 12 cases of malignant tumor. All the patients received plain and enhanced scans, and arterial reconstruction MPR. Results： Benign lesions is given priority to with single room capsule, capsule wall nodules in 2 cases, llcases have separate, 6 cases appear more room. Cystic wall, separated and nodules appear mild reinforcement. Malignancies appear cystic or solid, The boundary is not clear, Internal uneven den- sity, separation of uneven thickness, size wall nodule. The capsule wall and wall nodule obvious enhancement, 2 cases with aseites. 2 cases of cystic wall is a bit thick, confirmed by pathology serous cystic carcinoma. Conclusion： Serous cystic ade- noma mostly in single capsule and the capsule wall inforcement is not obvious. Serous eystadenoeareinoma is given with mixed cystic or solid, has the obvious early strengthening. Using 16 SCT scanning can judge the character of ovarian serous tumour.
