Disseminated life threatening Nocardia otitidiscaviarum infection in a young female with newly diagnosed systemic lupus erythematosus, case report and review of literature

Abstract

Infection due to Nocardia is reported mainly in immunocompromised patients. It usually presents as a pulmonary or disseminated disease with a predilection for the brain. Infections are a rare etiology of intracranial vascular aneurysms. Herein we report a case of disseminated Nocardia otitidiscaviarum (N. otitidiscaviarum) in a young female newly diagnosed with systemic lupus erythematosus (SLE) complicated by the development of an infectious intracranial aneurysm. To the best of our knowledge this is the fourth case of nocardial infection-related intracranial aneurysm and the second case of N. otitidiscaviarum infection to be reported in a patient with systemic lupus erythematosus. Features of previously reported N. otitidiscaviarum related intracranial aneurysm are reviewed.
