A case of acute onset headache and visual loss
Abstract
Granulomatosis with polyangiitis (GPA) is a multisystem autoimmune disorder. Typically, GPA presents with upper airway, pulmonary, and renal symptoms; an initial presentation limited to central system involvement (CNS) is rare. This case report describes a 54-year-old woman who presented with persistent daily headaches and a visual defect. Investigation revealed meningeal inflammation and optic neuritis demonstrated by magnetic resonance imaging and positive serine proteinase-3 ANCA serology diagnostic of GPA. She had a dramatic clinical response to corticosteroids. This case highlights a rare initial presentation of GPA with CNS manifestations.
