Overview

Tick-born Central European encephalitis may be accompanied by myeloradiculitis symptoms in up to 5% of patients. We report a case of a 48-year old woman, who was at first hospitalized for unspecified meningitis, when all common neuroinfections were excluded –⁠ including tick encephalitis –⁠ and after improvement she was discharged home. One month later she was admitted at the department of neurology with severe tetraparesis, muscular pain, without sensory deficit. Diagnosis of myelopolyradiculitis with only motor neurons and anterior roots lesion was done according to clinical findings and EMG. MRI findings confirmed our diagnosis and titer antibodies against tick-encephalitis were considerably positive, though the woman was properly vaccinated. Two months later and after supportive medication and intensive rehabilitation the patient began to walk with support.

Key words:
Tick-born Central European encephalitis –⁠ myeloradiculitis –⁠ motor neuron lesion –⁠ EMG
