Abstract
Thyroid gland and orbit are rare sites of metastases in neuroendocrine tumors. We present an extremely rare case of rectal neuroendocrine tumor with metastases to thyroid gland and intra-orbital regions that demonstrated significant reduction in size and uptake of the lesions on somatostatin receptor based 68 Ga-DOTATATE PET/CT, following 177 Lu-DOTATATE peptide receptor radionuclide therapy. The case illustrates the efficacy of 177 Lu-DOTATATE peptide receptor radionuclide therapy for tumor cytoreduction, which can be considered as a promising treatment modality for somatostatin receptor expressing and tracer-avid metastatic lesions at multiple rare locations.
