Idiopathic bilateral segmental pulmonary artery aneurysm.

Abstract

Aneurysms of segmental pulmonary arteries are rare. They can be potentially fatal, but remain undetected in the majority of cases. A young person reported with massive hemoptysis, and a ruptured large segmental pulmonary artery aneurysm of the left lung was identified as the cause. Incidentally a smaller aneurysm on the segmental artery of the right lung was noticed. The case is of rare occurrence, and the urgency of intervention on the left lung with consideration of an aneurysm on the right lung makes this case challenging. The clinical decision making for the choice of procedure for this rare and emergent situation is presented.
