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.
一位 56 岁男性，近期被诊断为蝶岩部类癌肿瘤，接受 Ga-DOTA-TOC PET/CT 扫描检查。除了类癌肿瘤中 Ga-DOTA-TOC 适度增加的摄取，扫描还显示右侧腮腺内一个额外病变中 Ga-DOTA-TOC 摄取明显增加和局灶性摄取。明显不同的 Ga-DOTA-TOC 摄取亲和力提示不同的病因，组织学检查显示为多形性腺瘤。
