Microscopic polyangiitis: an unusual neurologic complication.
ABSTRACT Microscopic polyangiitis is a systemic necrotizing vasculitis of the small vessels. Its typical clinical manifestations are rapidly progressive glomerulonephritis and alveolar hemorrhage. We describe a 30-year-old woman with rapidly progressive glomerulonephritis. Seven years later, she presented with partial loss of motor and sensory function in both lower limbs with sphincter dysfunction. This is the first reported case of epidural inflammation ascribed to microscopic polyangiitis. Possible mechanisms include auto-immune disease.
