68Ga-DOTA-TOC Uptake in Pleomorphic Adenoma

Clin Nucl Med. 2018 Jul;43(7):524-525. doi: 10.1097/RLU.0000000000002133.


A 56-year-old man who was recently diagnosed with a carcinoid tumor of the os petrosum was referred for a Ga-DOTA-TOC PET/CT scan. Besides the moderately increased Ga-DOTA-TOC accumulation in the carcinoid tumor, the scan showed strongly increased and focal Ga-DOTA-TOC uptake in an additional lesion in the right parotid gland. The markedly different Ga-DOTA-TOC avidity suggested a different etiology, and histological examination demonstrated a pleomorphic adenoma.
