title: Selective IgA deficiency with recurrent vasculitis of the central nervous system.
abstract: We describe an unusual case of selective IgA deficiency complicated by recurrent vasculitis of the central nervous system (CNS). The patient suffered from two episodes of CNS vasculitis, one of which was located in the cerebrum and the other in the cerebellum. The vasculitic process resulted in brain tumor-like lesions shown by computed tomography. There was no evidence of associated connective tissue diseases. Vasculitis in other organs or tissues was not noted. This is the first detailed description in the English literature of pathologically proven CNS vasculitis in a patient with selective IgA deficiency. Our report demonstrates that isolated CNS angiitis can be a rare clinical feature of selective IgA deficiency.
