case_images: Magnetic resonance imaging sagittal T2 image of the cervical and thoracic spine in June 2019 revealing intramedullary enhancement over the thoracic T2 to T4 regions. See blue arrows. Histology subsequently confirmed ependymoma. No intramedullary lesions were noted in the cervical spine.

case_images: Following a T3 to T4 laminectomy, this diagnosis ependymoma was confirmed [Figure 1].
case_images: Magnetic resonance imaging sagittal T2 image of the cervical and thoracic spine in August 2019 revealing new intramedullary enhancement over the cervical C2-3 region before treatment with steroids and immunosuppressive agents. See red arrow. The blue arrow indicates the post-surgical excision site for the thoracic ependymoma.

case_images: The repeat neuroaxis MR imaging (MRI) studies documented a new C2-C3 intramedullary his signal lesion [Figure 2].
case_images: Magnetic resonance imaging sagittal T2 image of the cervical spine in May 2021 during the neuromyelitis optica flare before medical treatment revealing significant cord swelling from C2 to C7 as illustrated by the blue arrows.

case_images: NMO lesion. Nevertheless, 18 months after that, he again presented with another NMO lesion (cervical MR with extensive patchy enhancement of the cord from C2 to C7 with diffuse cord swelling) now contributing to an acute quadriparesis [Figure 3].
case_images: Magnetic resonance imaging sagittal T2 image of the cervical spine in May 2021 after medical treatment revealing significant cord swelling reduction from C2 to C7.
