title: Percutaneous CT-guided radiofrequency ablation of symptomatic bilateral adrenal metastases in a single session.
abstract: Percutaneous computed tomography (CT)-guided radiofrequency (RF) ablation has been used in the palliative treatment of symptomatic bilateral adrenal tumors, often with each tumor addressed separately over the course of multiple treatment sessions. In the present case, a 71-year-old man with a diagnosis of lung cancer and painful bilateral metastases to the adrenal glands underwent percutaneous CT-guided RF thermal ablation of both adrenal masses in a single session (left adrenal mass, 4.7 cm; right adrenal mass, 4.3 cm), without occurrence of blood pressure instability or other acute complications. Measurement of plasma levels of cortisol, adrenocorticotropic hormone (ACTH), and glucose before and after RF ablation revealed transient changes that suggested preservation of endocrine feedback mechanisms. The patient experienced marked relief in pain bilaterally. By 5 days after the procedure, cortisol, ACTH, and glucose levels returned to preprocedural levels. On further follow-up at 6 months, the patient noted a lack of endocrine sequelae and continued pain relief.
