Confirmation of Intracranial Neuroendocrine Metastasis Utilizing ⁶⁸Ga-DOTATATE PET/CT

Abstract

Neuroendocrine tumors (NETs) are rare neoplasms with an exceedingly low incidence of intracranial metastasis. We present a 79-year-old female with a biopsy-proven pulmonary neuroendocrine tumor who presented with an intracranial mass in the posterior fossa that was DOTATATE avid on a ⁶⁸Ga-DOTATATE PET/CT, facilitating the rare diagnosis of intracranial NET metastasis. The case highlights the utility of advanced imaging techniques in differentiating intracranial NET metastasis from other etiologies.
