Pulmonary mucormycosis causing a mycotic pulmonary artery aneurysm

Abstract

Mycotic pulmonary artery aneurysms requiring pneumonectomy are extremely rare. We present a severely breathless immunocompromised diabetic middle-aged female patient. CT pulmonary angiogram revealed a giant pulmonary artery aneurysm with impending rupture in the right lung. We did an emergency right pneumonectomy under cardiopulmonary bypass support. Histopathology report of the lung specimen confirmed mucormycosis. She received amphotericin B after the procedure. The patient had a prolonged postoperative hospital stay and succumbed to sepsis. Mycotic pulmonary artery aneurysm portends very high morbidity and mortality in immunocompromised patients.
