Solitary castrate-resistant prostate cancer metastasis to adrenal gland with concordant intense avidity on PSMA and FDG PET.

Isolated prostate cancer metastasis to the adrenal gland is rare. We report a case of concordant high uptake in a solitary adrenal metastasis on both prostate-specific membrane antigen and fluorodeoxyglucose positron-emission tomography in a patient with castrate-resistant prostate cancer. Good initial biochemical response was achieved with laparoscopic adrenalectomy.
