A case of infected intracranial aneurysm with Nocardia meningitis treated with endovascular therapy: Case report and literature review

Abstract

Cerebral mycotic aneurysms are rare and account for a small percentage of all intracranial aneurysms. Fungal aneurysms occur less often than bacterial aneurysms and are associated with increased morbidity and mortality. Risk factors include an immunocompromised state, prior hematologic or solid organ malignancy, and chronic chemotherapy or steroid use. We present the fourth known case of an intracranial infectious aneurysm associated with Nocardia infection in a middle-aged male patient with previous Nocardia meningitis, and the only known case treated with endovascular coiling of aneurysm. We offer a literature review, case presentation, discussion, and considerations for treatment and management of these patients.
