The c linica l significance of infundibular widening (junctional dilatation) of the origin of an intracranial artery has been a topic of debate; junc tional dilatation is considered preaneurysmal by some investigators and a normal variant by others. Aneurysm form ation or hemorrhage from an infundibulum rarely has been reported. A pati ent is reported in whom both aneu rysm development at the infundibulum and bleeding from thi s site are documented. This experi ence suggests the possible value… Expand
Intracranial aneurysm arising from infundibular dilation
TLDR
The authors describe a 55-year-old female patient presenting multiple intracranial aneurysms with a small one arising from an ID at the level of posterior communicating segment of ICA, the first description of such unusual combination in the English literature. Expand
Bilateral aneurysm formation developing from junctional dilatation (infundibulum) of the posterior communicating arteries. Case report.
TLDR
It is concluded that junctional dilatations, especially in young women with a history of aneurysmal rupture, should be carefully followed by angiography. Expand
First demonstration of resolution of an infundibulum by direct treatment of the arterial wall with Pipeline flow-diverting stent
TLDR
The first case of a disappearing infundibulum after a flow diverting stent was deployed across the infundIBulum during the treatment of an adjacent aneurysm is described, concur in the view that infundibia are at least pre-pathological lesions that may in certain circumstances require consideration for treatment. Expand
Infundibular widening mimicking anterior communicating artery aneurysm: report of 2 cases.
TLDR
Grayscale modification of 3D reconstruction images of preoperative digital subtraction angiography revealed the cases of the recurrent artery of Heubner and perforating artery of the ACoA arising from the apex of the infundibular widening. Expand
Infundibular Dilations and Subarachnoid Hemorrhage: to Treat or Not to Treat?
TLDR
The literature, and the own experience, do not support the treatment of infundibula, even in SAH patients, and treatment should be directed toward an associated aneurysm, not theinfundibulum. Expand
Progression of an arterial infundibulum to aneurysm: case report.
TLDR
Diagnostic and therapeutic questions regarding arterial infundibula and the need of a better understanding of those lesions are brought about. Expand
The progression of an infundibulum to aneurysm formation and rupture: case report and literature review.
TLDR
This case of a ruptured posterior communicating artery aneurysm that had developed at the site of a previously known IF in a 49-year-old hypertensive woman suggests that in certain cases, serial investigations may be indicated with IFs to detect aneurYSm formation and preempt rupture. Expand
A tiny bleb at Junctional Dilatation of the Posterior Communicating Artery as a Predisposing Factor for Development of a De Novo Aneurysm
TLDR
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. Expand
Evolution from an Infundibulum of the Posterior Communicating Artery to a Saccular Aneurysm
TLDR
The risk of evolution of an infundibulum to a saccular aneurysm may be increased and follow-up should be even more stringent in patients with other aneurYSm(s). Expand
Are infundibular dilatations at risk of further transformation? Ten-year progression of a prior documented infundibulum into a saccular aneurysm and rupture: Case report and a review of the literature.
TLDR
The case of a 60-year-old female who presented 10 years earlier with a subarachnoid hemorrhage caused by a left internal carotid artery aneurysm rupture is reported, showing another proof of the small but growing number of examples of infundibular transformation over time, as well as their risk of progression into saccularAneurysms and subsequent rupture.

Aneurysm developing on the infundibular widening of the posterior communicating artery.
TLDR
A patient had a subarachnoid hemorrhage in 1969 and nine years later, angiography demonstrated that the infundibular widening had enlarged and developed into an aneurysm, though unruptured. Expand
Radiographic and histologic demonstration of an aneurysm developing on the infundibulum of the posterior communicating artery. Case report.
TLDR
Histological examination, after a fatal subarachnoid hemorrhage from the aneurysm, demonstrated that it arose exactly at the site of narrowing of the funnel-shaped infundibulum. Expand
The clinical significance of junctional dilatation of the posterior communicating artery.
TLDR
It is concluded that a junctional dilatation is neither aneurysmal nor preaneurysmal and is probably not even a pathological entity. Expand
Angiographic and Histologic Changes in Infundibular Widening of the Posterior Communicating Artery
TLDR
A survey of a normal material of 1020 angiographies revealed bulging of the vessel wall at the typical site in 67 cases (SALTZMAN), and the appearance of the bulge corresponded in many cases with the funnel-shaped proximal part of the posterior cerebral artery. Expand
The value of repeat pan-angiography in cases of unexplained subarachnoid hemorrhage.
TLDR
Four-vessel angiography was repeated in 56 patients with confirmed subarachnoid hemorrhage in whom the initial investigation was negative and only one aneurysm was demonstrated, suggesting that to repeat pan-angiography is seldom justified unless further bleeding episodes occur. Expand
Normal cerebral arteriography in patients with spontaneous subarachnoid hemorrhage
TLDR
Improvements in neuroradiologic techniques, such as femoral catheterization, magnification angiography, oblique and basal projections, and subtraction most probably contribute to the improved yield of normal cerebral arteriograms. Expand
