Abstract

Primary small cell neuroendocrine carcinomas are extremely rare heterogeneous neoplasms. We present 68 Ga-FAPI (fibroblast activation protein inhibitor) PET/CT findings of small cell neuroendocrine carcinoma of the gallbladder in a 57-year-old woman. This rare gallbladder small cell neuroendocrine carcinoma demonstrated intense tracer uptake on 68 Ga-FAPI PET/CT. This demonstrates the potential value of 68 Ga-FAPI PET/CT for evaluation of gallbladder small cell neuroendocrine carcinoma.
