多排螺旋CT对囊性肾瘤的诊断价值

Diagnostic value of multi-slice CT in cystic nephroma

目的 探讨多排螺旋CT对囊性肾瘤的诊断价值。方法 回顾性分析7例经手术病理证实的囊性肾瘤的多排螺旋CT影像学特征。结果7例囊性肾瘤均为单侧单发,直径4.3-11.5cm。多排螺旋CT扫描病变显示为边界清楚的多房囊性病变,囊腔间无交通,囊内分隔光整,增强囊壁及囊液无强化。组织病理学显示所有病例的囊壁和分隔由纤维结缔组织构成,衬覆单层或多层立方上皮。结论 多排螺旋CT能准确显示囊性肾瘤的形态学特征,可为临床诊断提供准确的参考信息。

Objective To evaluate the value of multi-slice CT（MSCT）in the diagnosis of cystic nephroma. Methods CT of 7 patients with cystic nephroma confirmed surgically and pathologically were analyzed retrospectively. Results The cystic nephroma in all 7 patients was unilateral and solitary,and diameter of lesions was 4.3-1 1.5 cm. The MSCT scans showed the border of multilocular cystic lesions was clear,the locules did not communicate with each other,the septa was intact and smooth and enhancement of cyst wall and fluid was not noticed.Histopathology proved that the cyst wall and septa of the lesions were constituted by fibrous connective tissues with a single or multi layer cuboidal epithelium.Conclusion MSCT can provide accurate reference information for cystic nephroma diagnosis.
