  • Anti-myelin oligodendrocyte glycoprotein (anti-MOG) syndrome is an immune-mediated inflammatory condition of the central nervous system, which usually involves spinal cord and optic nerves. Herein, we studied the case of a 57-year-old female patient who presented with acute/subacute symptoms of sphincter dysfunction, paraparesis, and ocular pain. The patient was diagnosed with anti-MOG syndrome with findings resembling snake-eye appearance (SEA), characterized by nearly symmetrical round high signal intensity lesions located at anterior horns (gray matter) on T2-weighted image.

  • We describe a case of a 71-year-old male patient who experienced progressive bilateral proximal upper limb weakness and atrophy without sensory symptoms and signs over 5 years. Electromyography demonstrated denervation potentials and neuropathic motor unit action potentials on C5-C7 myotome muscles bilaterally. Cervical spine magnetic resonance imaging revealed engorged anterior epidural venous plexus, T2 hyperintensity localized to grey matter ("snake-eye" appearance) at C2-C6 vertebral level, and ventral epidural fluid collection from C6 to T8 vertebral level. This case indicates that bibrachial amyotrophy associated with epidural fluid leak should be suspected in patients presenting with progressive bilateral upper limb weakness and atrophy without sensory involvement.
