Mycotic aneurysm of a pulmonary artery in the left lower lobe - A rare complication of MRSA pneumonia: A case report

Year: 2025

Type: article

Abstract: Mycotic aneurysms are abnormal dilations of arterial vessels caused by infections. The most common pathogens responsible for mycotic aneurysms are species of Staphylococcus and Streptococcus. Mycotic aneurysms of the pulmonary artery associated with methicillin-resistant Staphylococcus aureus (MRSA) infections are rare. We present the case of a 52-year-old female nonsmoker who developed pneumonia, severe sepsis, and a progressive mycotic aneurysm of the pulmonary artery in the left lower lobe due to a MRSA infection. Following antibiotic therapy, the patient underwent a successful open left lower lobectomy. Post-surgery, her recovery was uneventful, and follow-up imaging showed the remaining left upper lobe with unremarkable post-lobectomy changes. We believe that anatomical lung resection can be a reliable and safe treatment option that ensures complete removal of a mycotic aneurysm arising from the pulmonary artery.
