Pulmonary Artery Pseudoaneurysm in Hyper-IgE Syndrome: Rare Complication With Successful Endovascular Management

Hyper-IgE syndrome also known as Job syndrome is characterized by elevation of circulating immunoglobulin (IgE) levels and is usually associated with recurrent bacterial infections of the skin and sinopulmonary tract. Though bacterial pulmonary abscess and pneumatocele formation have been described, pulmonary artery pseudoaneurysm in Job syndrome has not been reported in literature. Our report describes a case of large pulmonary artery pseudoaneurysm in a child with Job syndrome, who presented with massive hemoptysis. Emergent endovascular management was performed with percutaneous coil occlusion of the feeding artery.
