Comparative analysis of the MSCT characters and pathology of chromophobe renal cell carcinoma / 实用放射学杂志

ABSTRACT

Objective To explore the MSCT manifestations of chromophobe renal cell carcinoma (CRCC)and to improve its accu-racy of preoperative diagnose.Methods Clinical and MSCT finding were retrospectively reviewed in 14 patients with CRCC,which were confirmed by surgical pathology or biopsy.Results (1)On plain scanning,most of the CRCC lesions showed round or oval (86.7%,13/1 5)and isodensity (73.3%,1 1/1 5)mass;and the border of 66.7% (10/1 5)lesions were clear.53.3% (8/1 5)of the lesions were heterogeneous with lamellar cystic low density (8 lesions)and coarse ringed and/or foliated calcifications (4 lesions). (2)On contrast-enhanced sacanning,the CRCC lesions showed mild to moderate (86.7%,13/1 5)and heterogeneous (60%,9/1 5) enhancement,and 73.3% (1 1/1 5)of the lesions were persistent enhanced.(3)According to the pathology,80% (12/1 5)of the le-sions was the typical type,20% (3/1 5)was the eosinophilic type,and 0 was the hybrid type.Conclusion CRCC demonstrates cer-tain characteristics signs at MSCT examination.Lesion mostly shows well-circumscribed round or oval mass in the renal parenchy-ma,mild to moderate,heterogeneous and continuous enhancement on the contrast scanning.The diagnosis of CRCC should be con-sidered especially when the lesion has cystic change and coarse ringed and/or foliated calcifications.
