Systemic cytomegalovirus infection mimicking an exacerbation of Wegener's granulomatosis.

A patient with Wegener's granulomatosis developed a systemic cytomegalovirus infection that mimicked an exacerbation of her vasculitis including pulmonary infiltrates, renal insufficiency, and cutaneous necrotizing ulcers. All of her symptoms resolved with ganciclovir. Physicians should maintain a high index of suspicion for similar presentations in other patients with vasculitis with or without immunosuppressive therapy.
