Microscopic polyangiitis presenting with capsular warning syndrome and subsequent stroke.
A 55-year-old man developed ischemic stroke after three episodes of transient dysarthria and left hemiplegia, a typical manifestation of capsular warning syndrome. Magnetic resonance imaging of the brain showed bilateral basal ganglionic infarction. The patient had no significant risk of stroke. However, the systemic manifestations, an elevated titer of perinuclear anti-neutrophilic cytoplasmic antibody and a skin biopsy revealing leukocytoclastic venulitis confirmed the undrlying microscopic polyangiitis.
