Diagnostic accuracy of computed tomography-guided percutaneous biopsy of renal masses.
OBJECTIVE Modern imaging modalities increase the detection of small ( < or=4 cm ) renal tumors , of which about 20 % are benign . As a result , minimal invasive treatments , such as radiofrequency ablation and cryotherapy , and surveillance strategies are gaining popularity . Information that would be helpful when choosing the most appropriate management strategy for this patient group could be obtained from pretherapeutic image-guided biopsy . METHODS Under computed tomography (CT)-fluoroscopic guidance  78 patients with solid renal tumors prospect ively underwent 18-gauge core biopsy . In addition , using the same sheath , fine-needle aspiration was taken in 44 patients and analyzed cytologically . The renal masses were subsequently removed surgically and evaluated histologically . RESULTS Mean patient age was 63+/-13.5 yr ; mean tumor size was 4+/-1.8 cm . The sensitivity of  core biopsy and fine-needle aspiration for the detection of renal cell carcinoma ( RCC ) was 93.5 % and 90.6 % , respectively ; Fuhrman grade was correctly predicted in 76 % and 28 % and the correct histologic subtype was identified 91 % and 86 % , respectively . Cytology from fine-needle aspiration revealed a sensitivity in detecting malignant and benign lesions of 100 % and 75 % , respectively . Two of the renal tumors diagnosed as oncocytomas on core biopsy were hybrid tumors with scattered areas of oncocytomas and chromophobe RCC . Complications of CT-guided biopsy included one marginal pneumothorax , which resolved under conservative management , and four small perirenal hematomas detected at follow-up ultrasonography not requiring further therapy . CONCLUSION CT-guided percutaneous preoperative renal tumor biopsy had a high diagnostic accuracy , particularly in predicting malignancy
