CTICasesRecurrent Infective Endocarditis with Mycotic Pulmonary Aneurysms

Imaging findings
Initial cardiac CT showed thickening of aortic leaflets and a possible pseudoaneurysm. Lungs were clear. Twelve months later, a CT pulmonary angiogram (CTPA) revealed profound, diffuse changes in the lungs including multiple aneurysmal dilatations (mycotic aneurysms) of pulmonary arteries, some communicating with cavities. The pulmonary valve appeared very abnormal and thickened, with a pseudoaneurysm related to it (post-Ross procedure).
Key takeaways
This unfortunate case illustrates recurrent infective endocarditis and severe pulmonary complications, specifically massive mycotic pulmonary artery aneurysms, in an injecting drug user. It demonstrates the diffuse and life-threatening nature of such infections, including their impact on heart valves and the pulmonary vasculature. The patient's poor prognosis without surgical intervention underscores the severity.
