case_images: MR images of the proband. (A) T2-weighted fat-saturated coronal and (B, C) T2-weighted STIR axial images of the lower extremities. Diffuse hyperintensity (horizontal arrows) was seen symmetrically in the bilateral gastrocnemius muscles (Figure B, right lower limb; Figure C, left), which were considered edema due to muscle spasm resulting in the varus deformity of distal limbs, as shown in Figure (A). (D-E) Axial and Sagittal T2 flair images of the cervical spinal cord show disc herniation without spinal cord degeneration.

case_images: Electromyography did not indicate neurogenic lesions, while magnetic resonance imaging (MRI) revealed lateral compartment signal increase in the lower extremities (Figures 1B,C), which were considered edema due to muscle spasms. MRI of the brain was normal; however, the spine MRI showed a herniated cervical disc with compression of the dural sac (Figure 1D). There was no intramedullary degeneration (Figure 1E).
