目的分析囊性肾瘤的CT影像学特征。资料与方法回顾性分析经临床病理证实的6例囊性肾瘤的CT资料,并与病理和组织学表现对照分析。结果 6例均为单发,2例发生于左侧,4例发生于右侧。6例均表现为边界清晰,多房,囊性肿块,囊液CT值高于水。1例病灶内呈稍高密度,CT值为33 HU,后经病理证实为出血,增强扫描囊液无强化。1例CT表现为分隔不清,1例出现少许点状、条状钙化。结论肾脏囊性肾瘤影像学表现为边界清晰、多囊性病变、囊液CT值高于水,分隔较纤细,未见明显壁结节,分隔及囊性部分均无明显强化。
Objective To analyze the CT imaging features of cystic nephroma. Materials and Methods Retrospective analysis of CT data of 6 cases of cystic nephroma confirmed by clinicopathological and pathological and histological findings. Results 6 cases were single, 2 cases occurred in the left, 4 cases occurred in the right side. Six cases showed a clear boundary, multi-room, cystic mass, cyst fluid CT value higher than water. One case was slightly higher density lesions, CT value of 33 HU, after the pathological confirmed as bleeding, enhanced cyst fluid without enhancement. One case of CT showed segregation, a case of a little punctate, strip calcification. Conclusions The imaging features of renal cystic nephroma are clear and polycystic lesions. The cyst fluid CT value is higher than that of water. The cystic neoplasms are slender, with no obvious wall nodules. The separation and cystic parts are not obviously enhanced.
