Tick bite meningoradiculitis. Ten cases.

A study was undertaken on 10 cases of meningoradiculitis following a tick bite. All patients developed neurologic manifestations and C.S.F. abnormalities. Electrophysiologic studies demonstrated decreased motor potential amplitude and normal motor conduction velocity suggesting distal axonal involvement. Radicular lesions were suspected due to the presence of delayed F waves. This is the first study to confirm these electrical findings by histologic examination of the superficial peroneal nerve of the leg during the course of thick meningoradiculitis.
