title: Diagnostic pitfalls associated with a large true posterior communicating artery aneurysm: a case report.
abstract: True posterior communicating artery (PCoA) aneurysm is an aneurysm that originates from the PCoA, and large or giant true PCoA aneurysms are rare. We report a case of a large true PCoA aneurysm successfully clipped after anterior clinoidectomy and discuss the diagnostic pitfalls associated with this rare clinical entity.
