[Granulomatous angiitis of the basilar artery related to herpes zoster of the 7th cranial nerve].

Granulomatous angiitis of the central nervous system is an uncommon condition characterized by vascular wall necrosis, inflammatory exudate and development of giant cells in medium and small size vessels. The pathogenesis of this disease remains unknown, but it has been associated with immune complexes, mechanical factors and infection by the varicella-zoster virus. We report a young patient who presented with herpes zoster involving the VII cranial nerve and contralateral hemiplegia.
