目的：探讨肾脏嫌色细胞癌(CRCC)的 MSCT 表现,旨在提高术前诊断的准确率。方法回顾性分析经手术或穿刺病理证实为 CRCC 的14例患者的临床及术前 MSCT 资料。结果(1)CT 平扫 CRCC 多呈圆形或椭圆形(86.7%,13/15)等密度(73.3%,11/15)肿块；66.7%(10/15)的病灶边界清晰；53.3%(8/15)的病灶密度不均,主要表现为片状囊性低密度影(8个病灶)、粗大的环状或/和片状钙化影(4个病灶)。(2)CT 增强扫描表现为轻中度(86.7%,13/15)不均匀(60%,9/15)强化的肿块影,73.3%(11/15)的病灶呈持续强化。(3)病理上,经典型占80%(12/15),嗜酸型占20%(3/15),无混合型。结论 CRCC 的 MSCT 表现有一定的特点,多为肾实质内边界清晰的类圆形肿块,增强扫描呈不均匀轻中度持续性强化,尤其当病变伴有囊变坏死且环状或片状钙化时应考虑本病的可能。

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.
