title: Progressive multifocal leukoencephalopathy complicating treatment for Wegener's granulomatosis.
abstract: We describe a man treated with cyclophosphamide and prednisone for Wegener's granulomatosis who developed biopsy proven progressive multifocal leukoencephalopathy (PML). Upon discontinuation of immunosuppression he made a dramatic recovery. As immunosuppressant use is increasing we draw attention to this potentially fatal, but reversible neurologic disease.
