A tiny bleb at Junctional Dilatation of the Posterior Communicating Artery as a Predisposing Factor for Development of a De Novo Aneurysm

Abstract

Formation of de novo aneurysm from a junctional dilatation at the origin site of the posterior communicating artery (PcomA) has been rarely reported. In this case report, three females in sixth decades of age developed a de novo aneurysm from the junctional dilatation of the PComA with a tiny bleb-like lesion over 5 years after initial presentation.
