    FIGURE 1.

    (A and B) On T1-weighted axial CT image, lesion in pineal gland region was isointense before contrast administration (A) and enhanced afterward (B). (C) Sagittal images of dorsolumbar spine after contrast administration showed intensely enhancing sheetlike soft tissue in epidural space.

  • FIGURE 2.
    FIGURE 2.

    (A) 18F-FDG PET/CT maximum-intensity-projection image revealed abnormal uptake in lumbar spine region. (B–E) Transaxial (top) and sagittal (bottom) CT (left) and PET/CT (right) images of head revealed avidly enhancing nodular lesion (∼1.4 × 1.3 cm) in pineal gland (arrows). (F and G) Sagittal CT (left) and PET/CT (right) images revealed increased uptake in ill-defined densities in spinal canal extending from L1 to L5 (arrows).
