A Rare Case of Peripheral Pulmonary Artery Aneurysm and Cavitating Pneumonia in a Patient with COVID-19 Managed with an Endovascular Method

Peripheral pulmonary artery aneurysm (PAA), being a rare condition, is considered extremely rare following coronavirus disease 2019 (COVID-19). We present a 58-year-old male who presented with fever, malaise, and dry cough. SARS-CoV-RNA transcription-mediated amplification test was positive for the patient. After 2 days, he developed hemoptysis and back pain, and a CT scan revealed a pulmonary aneurysm, evidence of alveolar hemorrhage, and Necrotizing pneumonia. He was scheduled for pulmonary artery angiography. The angiography confirmed a fusiform aneurysm and partial coiling of the aneurysmal sac, and indoor and backdoor embolization was performed. In the follow-up, a CT scan showed complete thrombosis of the aneurysmal sac, and the patient was free of symptoms. Peripheral PAAs can show a variety of symptoms. They can even be asymptomatic. The infectious pathologies of this condition are less common than the other. COVID-19 is an extremely rare pathology. To the best of our knowledge, this is the first case of necrotizing pneumonia and peripheral PPA in an adult. Moreover, it was followed by COVID-19. A vital takeaway note for physicians is to consider PAAs as a complication when treating COVID-19 patients who don't show signs of improvement or even show signs of exacerbation.
