Acute Cerebral Venous Sinus Thrombosis: A Rare Complication of Primary Varicella Zoster Virus Infection.

Varicella-Zoster is a benign self limiting exanthematous illness in pediatric population which can rarely present with severe neurological manifestations such as cerebral venous thrombosis(CVT).We report the case of a 17-years old adolescent male with left hemiparesis, cranial nerve palsies associated with primary Varicella infection. MRI revealed cerebral venous thrombosis involving right transverse sinus, sigmoid sinus, internal jugular vein and infarct involving right cerebral hemisphere, Midbrain and Pons. The patient responded well to Acyclovir, cerebral decongestants and oral anticoagulant therapy.CVT is a rare but the most life threatening complication following primary Varicella infection and early diagnosis is essential for proper management of the patient.
