Abstract:
Objective To investigate the CT features of renal oncocytoma(RO),and to analyze the causes of misdiagnosis.Methods CT and clinical data of 1 2 patients with RO confirmed by surgery and pathology were analyzed retrospectively,the CT features and the causes of misdiagnosis before operation were analyzed and summarized.Results According to CT features before operation,among the 1 2 cases of RO,9 were misdiagnosed as renal carcinoma,3 were considered as benign occupying lesions.There were 6 cases located in the left kidney and 6 in the right kidney.Seven cases showed round mass and 5 showed irregular mass.Plain CT showed homogeneous masses in 6 cases and heterogeneous masses in 6 cases.Enhanced CT showed masses with homogeneous enhancement in 2 cases and masses with progressive enhancement in 10 cases.The attenuation value of parenchymal enhancement ranged from 41 to 143 HU (mean 90.17 HU).Seven cases had central scar syndrome,of which 1 case had calcification in the scar.One case showed segmental enhancement inversion,8 showed conical interface and 5 had holding ball signs.Conclusion The CT features of RO is central scar syndrome, segmental enhancement inversion,conical interface and holding ball sign,etc,but the definitive diagnosis still rely on pathology.
