The case of a white adult male suffering from herpes zoster following lumbar puncture is reported. The herpetic eruption developed eight days following the trauma of lumbar puncture. The herpes zoster cleared up completely after one week of described treatment. An explanation of the neurological basis of the herpes zoster has been submitted. This is a rare condition considering the millions of lumbar punctures routinely done, in which no mention has ever been made of such an occurrence.Abstract Teaser
