We report the unique case of a patient with previously proven non‐functional PanNET and Graves' disease with thyroid nodules. The patient had elevated intranodular calcitonin, but no MTC or c‐cell hyperplasia on thyroidectomy. They were found to have calcitonin secreting PanNET. This case presents a false‐positive intranodular calcitonin.
