title: Pulmonary mycotic pseudo-aneurysm with a prior history of ventricular septal defect. Case report with review of literature.
abstract: In general aneurysms of the pulmonary arteries are less frequent than intracranial, aortic or other vascular locations. Infectious causes include bacteria such as Staphylococcus sp and Streptococcus sp, mycobacteria, Treponema pallidium (syphilis) and rarely fungi. We report a 7 year old female with two right-sided parahilar pseudo-aneurysm of fungal origin with a prior history of ventricular septal defect. Pulmonary mycotic pseudo-aneurysms are very rare and require a high suspicion to diagnose. If a patient is still symptomatic for fever and cough for a long time, and consolidation on x-ray is not improving on antibiotics, contrast-enhanced computed tomography is indicated. It can be suspected that the "friable mass attached to ventricular septal defect patch" was a source of fungeal emboli to pulmonary arteries thus giving weight to the infective endocarditis etiology. A prior history of ventricular septal defect repair could favour fungal endocarditis.
