Adrenal Castleman Disease on 99mTc-HYNIC-TOC Scan and FDG PET/CT

Clin Nucl Med. 2021 Jan;46(1):71-73. doi: 10.1097/RLU.0000000000003271.

Abstract

Adrenal Castleman disease is very rare. We reported image findings of a right adrenal mass in a 75-year-old man on Tc-HYNIC-TOC scan and FDG PET/CT. There was obviously elevated Tc-HYNIC-TOC activity, but the intensity of FDG activity was remarkable. Pheochromocytoma was initially suspected. However, pathology from resected specimen showed adrenal Castleman disease.
