ABSTRACT
Objective To evaluate the differentiation and diagnosis of benign renal tumors and tumor-like lesions. Methods The data of 49 cases of benign renal tumors and tumor-like lesions were retrospectively analyzed.All the 49 cases underwent B-ultrasonography and CT;14 cases underwent MRI.The clinical manifestation,imaging features and the pathological results were evaluated.21 cases of benign renal tumors and tumor-like lesions were misdiagnosed as renal carcinoma and underwent nephrectomy.28 cases underwent nephron-sparing tumor excision. Results There was no specificity of the clinical presentation in all the cases.CT and MRI showed that angiomyolipoma had imaging features of intra-tumoral fat.Color Doppler ultrasonography showed the specific features of renal arterio-venous fistula and renal artery aneurysms.The other imaging features of benign renal tumors and tumor-like lesions had no specificity.28 cases who underwent nephron-sparing surgery were followed up for 1 to 9 years and had no relapse.Their renal functions were normal. Conclusions Bulltrosonography,CT and MRI are contributive to the diagnosis and treatment of benign renal tumors and tumor-like lesions.Using nephron-sparing surgery for indeterminate renal masses may reduce misdiagnosis and unnecessary nephrectomy.
