Unilateral adrenal metastasis from non–small-cell lung cancer demonstrating very high FDG uptake with a standardized uptake value in excess of sixty

Unilateral Adrenal Cryptococcosis on FDG PET/CT

A 70-year-old man with T-cell deficiency experienced continuous right waist pain and a low degree of fever. Abdominal CT found a large right adrenal mass. FDG PET/CT imaging was acquired to identify the nature of this likely malignant mass and search for potential metastases. The images revealed increased FDG activity in the mass. The patient received right adrenalectomy. Postsurgical pathological and microbial examination demonstrated adrenal cryptococcosis.

Gallbladder carcinoma metastasizing to adrenal gland: a rare site demonstrated with (18)F-FDG PET/CT

Adrenal metastases have commonly been reported in a wide variety of cancers but not in gallbladder cancer. We here present a case of a 45-year-old male patient with gallbladder carcinoma where left adrenal metastasis was detected on staging F-FDG PET/CT. This was confirmed histopathologically. F-FDG PET/CT can have a significant impact on management of patients with gallbladder carcinoma by demonstrating rare sites of metastasis.
