Aspiration cytology of simultaneous bilateral adrenal metastases from renal cell carcinoma. A case report and review of the literature.

We report the computerized tomography and ultrasound-guided aspiration cytology results in the first case of renal cell carcinoma with bilateral adrenal involvement. The adrenal metastases were evident clinically 6 years after radical nephrectomy and were treated successfully by an operation. Aspiration cytology under computerized tomographic and sonographic guidance is an excellent procedure to evaluate enlarged adrenal glands in patients with renal cell carcinoma or other malignant neoplasms.
