多囊性肾细胞癌超声、CT及MR影像学表现

Appearances of the sonographic,CT and MR imaging of multilocular cystic renal cell carcinoma

目的探讨多囊性肾细胞癌(MCRCC)超声、CT及MR影像学表现及多种影像学方法在诊断及鉴别诊断中的作用。方法病理结果为多囊性肾细胞癌者18例,收集其超声、CT及MR的图像资料,观察肿块形态特征和超声、CT及MR图像特征。结果18例均显示肿块为包膜完整、多囊、间隔薄。彩色多普勒超声、增强CT和增强MR显示肿块包膜及间隔有彩色血流信号或强化。结论MCRCC有特征性影像学表现。超声、CT及MR成像有助于MCRCC的诊断及鉴别诊断。

Objective To explore appearances of sonographic,CT and MR imaging of multilocular cystic renal cell carcinoma（MCRCC）and its diagnosis and differential diagnosis.Methods Eighteen patients with MCRCC diagnosed in pathology were found and their sonographic,CT and MR images were collected.The characters of sonographic,CT and MR imaging were observed.Results The common characters such as intact walls,multiple cysts with thin septa were observed in all 18 patients.Colored blood flows in walls and septa were observed on colored Doppler flow imaging（CDFI）.Intensified walls and septa were observed on CT and MR imaging.Conclusion There are characteristic appearances of MCRCC in sonographic,CT and MR imaging.Ultrasonography,CT and MR are effective in diagnosing or differential diagnosing of MCRCC.
