A 44-year-old woman with right cerebellopontine angle metastatic small cell neuroendocrine carcinoma underwent 18F-FDG and 18F-NOTATATE PET/CT scans. 18F-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 18F-FDG PET/CT. Copyright © 2022 Wolters Kluwer Health, Inc. All rights reserved.
