Lumbar Radiculitis as a Complication of Vaccination against Tick-Borne Encephalitis: A Differential Diagnosis of Low Back Pain and Nerve Root Compression

Abstract EN

Serious adverse reactions following immunisation with adult tick-borne encephalitis (TBE) vaccines are rare, but when they occur, they most frequently involve the nervous system.

We present a case of a female patient who developed a sensory and motor L4 monoradiculopathy following self-injection of an inactivated vaccine against TBE in the ipsilateral quadriceps muscle.

The motor and sensory L4 dysfunction vanished after 12 months.

TBE vaccine-induced radiculopathy should be considered as a mimic of spinal root compression.
