Abstract | INTRODUCTION: PATIENT FINDINGS: We present an 82-year-old female, in whom an asymptomatic cerebellar metastasis from PTC was diagnosed by means of Tc-99m- EDDA/HYNIC-TOC scintigraphy four years after the initial diagnosis. She was previously treated with total thyroidectomy and regional lymph node dissection, followed by three cycles of radioiodine therapy. Despite persistently elevated thyroglobulin, no specific radioiodine accumulation was found in the whole body post-treatment scan. Tc-99m- EDDA/HYNIC-TOC scintiscan revealed foci of increased tracer uptake in the lungs, cervical lymph nodes, and a single focus in the head. Thus, therapy with octreotide LAR was initiated. The patient died four months later due to disseminated PTC. SUMMARY: In this paper, a patient with asymptomatic previously unknown non- iodine avid cerebellar metastasis of PTC diagnosed by means of scintigraphy using somatostatin analogue Tc-99m- EDDA/HYNIC-TOC is reported.
