Abstract
CONTEXT: Guillain-Barré syndrome (GBS), acute cerebellitis and transverse myelitis are rare complications of COVID-19 infection separately. The combination of these three, however, has not yet been reported. FINDINGS: We present an atypical case (42-year-old man) that developed acute ascending flaccid paraparesis, ataxia and urinary retention two weeks after COVID-19 infection. Neurological examination revealed distal and proximal weakness (4/5) on lower extremities, decreased tendon reflexes, sixth cranial nerve palsy and dysmetria without sensory disturbance. His cranial MRI showed cerebellitis whereas the spinal MRI showed transverse myelitis at the T11/12 level. Albuminocytologic dissociation was present in the cerebrospinal fluid. The nerve conduction study was concordant with early findings of GBS. He recovered well after corticosteroid treatment without needing any immunotherapy. On day seven of hospitalization, the modified Rankin Scale score was 0. CONCLUSION: COVID-19 infection may present with a combination of neurological manifestations such as cerebellitis, transverse myelitis and GBS. This patient presented significant functional recovery after treatment with corticosteroid without immunotherapy.
