case_images: (a) Atrophy of the muscles of the forearm with preservation of the brachioradialis (Oblique atrophy sign) (black arrow). (b) Atrophy of the intrinsic muscles of the hand (thenar, hypothenar, and dorsal interosseous muscles) (black arrows). (c) Needle electromyography of the triceps revealing high-amplitude, polyphasic action potentials, fibrillation potentials, and reduced recruitment.

case_images: (a) Sagittal T2-weighted flexion magnetic resonance imaging (MRI) image demonstrating the anterior displacement of the posterior dural wall along with spinal cord compression and enlargement of the posterior epidural space (Crescent moon sign) (yellow arrow). (b) Sagittal T2-weighted extension MRI image demonstrating the presence of abundant cerebrospinal fluid anterior to the spinal cord and no spinal cord compression.

case_images: Dynamic magnetic resonance imaging (MRI) revealed anterior displacement of the posterior dural wall during flexion and spinal cord compression at C3-C6 levels along with a crescent-shaped enhancement of the posterior epidural space (Crescent moon sign), [Figure 2].
