Single-Session CT-Guided Percutaneous Microwave Ablation of Bilateral Adrenal Gland Hyperplasia Due to Ectopic ACTH Syndrome.

Bilateral adrenalectomy is currently the only available treatment for adrenocorticotropic hormone (ACTH)-dependent Cushing's syndrome (ectopic ACTH syndrome) that is refractory to pharmacologic therapy. We describe two patients with refractory ectopic ACTH syndrome who were treated with CT-guided percutaneous microwave ablation of both hyperplastic adrenal glands in a single session: O ne was not a surgical candidate, and the other had undergone unsuccessful surgery. Following the procedure, both patients achieved substantial decreases in serum cortisol, symptomatic improvement, and decreased anti-hypertensive medication requirements.

Benign metastasizing pleomorphic adenoma presenting as a solitary kidney mass: imaging features.

Benign metastasizing pleomorphic adenoma is a rare condition that occurs in patients with a prior history of pleomorphic adenoma of the salivary glands. Metastases to the kidney are extremely rare, and, to the best of our knowledge, their imaging appearance on multiple cross-sectional imaging modalities has not been described. We present a solitary metastasis to the kidney in a 40-year-old woman.
