case_images: 18F-FDG PET/CT: Increased tracer uptake in intracranial and paravertebral regions (A: MIP image). On fused axial images there is increased tracer uptake in suprasellar region (B) and pineal gland region (C) and cerebellar vermis region (D). Sagittal fused image (E) reveals increased tracer uptake in pineal gland (arrow head) and suprasellar regions (arrow), and cervical nerve roots (red arrow). On sagittal PET image there is increased tracer uptake in cervical spinal cord, lumbar, and sacral nerve roots (F)

case_images: The findings indicated focal FDG uptake in the pineal gland, suprasellar region, cerebellar vermis, fourth ventricle, cervical spinal cord, and multiple nerve roots (Figure 2). A) showed increased FDG uptake in the brain's pineal gland region. Axial hybrid PET/CT images demonstrated increased FDG uptake in the suprasellar region (Figure 2; B), pineal gland region (Figure 2; C), and cerebellar vermis (Figure 2; D). The sagittal hybrid PET/CT image (Figure 2; E) revealed increased FDG uptake in the pineal gland, suprasellar regions, and cervical nerve roots (arrowheads). The sagittal PET image (Figure 2; F) showed increased FDG uptake in the cervical spinal cord and lumbar and sacral nerve roots (Figure 3).
