title: Neurological complications of varicella: a report of two cases.
abstract: Varicella (chickenpox) is the primary infection of Varicella-Zoster virus, characterized by generalized vesicular eruption, fever and mild constitutional symptoms. Chiefly infecting children of 1 to 14 years of age, the disease has been almost neglected because of its inevitable and benign outcome. Adults are rarely infected with an incidence of less than 20%. These two cases are presented of normal adults with marked neurological complications 10 and 14 days, respectively, following typical skin eruption of varicella. The first case developed transverse myelitis and the second, an encephalomyelitis. Neurological complications are very rare post-varicella infection. Although prognosis is good and complete recovery is the rule, still some morbidity with neurological sequelae and mortality have been reported. The present cases had extensive neurological deficit, despite aggressive treatment, making a high index of suspicion for differential diagnosis in patients who present with encephalitis. Especially following the typical exanthema of varicella, this possibility is emphasized and the literature is reviewed.
