case_images: Magnetic resonance imaging of the cervical spine. (A-C) Sagittal and (F) axial T2-weighted images (T2WIs) show a hypointense heterogenous space-occupying lesion (arrows) causing compression and anterior displacement of the spinal cord (F, asterisk) in the right posterolateral epidural space. (D) Sagittal T1-weighted image (T1WI) depicts hyperintense areas (arrows) within the mass that may represent hemorrhage. Note the contrast enhancement within the mass on the (E) sagittal and (G) axial post-contrast T1WIs. (H) Postoperative sagittal T2WI demonstrates total resection of the lesion.

case_images: Cervical spinal magnetic resonance imaging was performed, and a space-occupying lesion in the right posterolateral epidural space was detected in the C4-T1 segments (Fig. 1A-1G). Subsequently, the patient underwent surgery and the mass was completely excised (Fig. 1H).
case_images: (A) Dystonic posture of the patient's hand, characterized by flexion of the 3rd, 4th, and 5th metacarpophalangeal and proximal interphalangeal joints. (B) After botulinum toxin A injection, the flexion posture is partially improved.

case_images: She had a dystonic right-hand posture characterized by adduction and flexion of the 3rd, 4th, and 5th metacarpophalangeal (MCP) and proximal interphalangeal (PIP) joints (Fig. 2A).
