Mycotic pulmonary artery aneurysms and septic pulmonary emboli in infective endocarditis: A rare case report and review of imaging findings

Within the heterogeneous spectrum of pulmonary vascular disorders, pulmonary artery aneurysms and pseudoaneurysms remain among the least frequently encountered yet most clinically consequential entities. Despite their low incidence, they carry a significant risk of life-threatening complications and pose a considerable diagnostic and therapeutic challenge requiring timely clinical intervention. This report describes the clinical presentation of an 18-year-old female patient with a previously established diagnosis of congenital ventricular septal defect, who developed a mycotic pulmonary artery aneurysm in the context of infective endocarditis complicated by septic emboli.
