Primary Neuroendocrine Carcinoma of Pineal Gland with Extensive Meningeal Metastasis Detected by 18F-NOTATATE PET/CT.

Primary neuroendocrine tumor of the pineal gland is a rare disease. A 44-year-old woman with right cerebellopontine angle metastatic small cell neuroendocrine carcinoma underwent 18 F-FDG and 18 F-NOTATATE PET/CT scans. 18 F-NOTATATE PET/CT showed intense uptake in the pineal gland lesions and multiple foci of intense focus of uptake in the intracranial leptomeningeal and whole spinal canal. However, the lesions are less impressive on 18 F-FDG PET/CT.
