Abstract
Neuroendocrine tumor (NET) typically spreads to the liver, lymph nodes, lungs, and skeleton. Brain metastasis in NET is uncommon. Therefore, each case of detected brain metastases in NET is crucial for the development of treatment guidelines for these types of tumors. We present a unique case of triple tumors (NET, papillary thyroid carcinoma, and schwannoma) in a single patient who presented with neurological symptoms and somatostatin receptor-avid T2 hyperintense multiple metastatic brain lesions from NET on 68 Ga-DOTATATE-PET/CT scan and brain MRI. Despite the rarity of brain metastases in NET, we conclude that the presence of neurological sign or symptoms and/or the detection of somatostatin receptor-avid brain lesions in patients with NET should raise suspicion of brain metastases.
