“…In a further 10, there was a uni lateral absence, see table I. In the 12th case the left posterior cere bral artery received all its blood supply from the left internal At the origin of the posterior communicating artery from the internal carotid an infundibular widening, described by Saltzman (1959) and Hassler and Saltzman (1959), was more or less pronounced in several cases. In addition, in some of these cases and in a few others, the present author observed a similar although less pro nounced widening of the other (posterior) end of the posterior communicating artery where it joins the posterior cerebral artery ( fig.…”

“…The observation made by the present author, that the posterior com municating artery is more commonly absent in adults, accords with the postnatal atrophy of this artery. Saltzman (1959) was the first to describe an infundibular widen ing of the origin of the posterior communicating artery where it diverges from the internal carotid. He demonstrated the widening in 67 out of 1020 patients examined by carotid angiography.…”

“…It is noted in approximately 7% of otherwise normal angiograms. [21] Its significance, particularly from the point of view of it being pre-aneurysmal, remains uncertain. Hassler and Saltzman [5] looked at the histology of 21 cases of infundibular widening and found that a significant proportion demonstrated defects in the internal elastic lamina as well as defects in the media, such changes being typical of aneurysm.…”

We present details of a family who show a high incidence of both intracranial saccular aneurysm and infundibular widening. Familial aneurysms are compared with aneurysms occurring in the general populations with regard both to site distribution and age of onset of symptoms. The possibility of infundibular widening being preaneurysmal is further discussed. It is highly likely that the mode of inheritance in familial cases is one of dominance.

A 67-year-old female with a history of hypertension and cerebral infarction presented with subarachnoid hemorrhage (SAH) (Hunt and Kosnik grade 4). Brain computed tomography (CT) revealed a clot dominantly on the right (Fisher's classification Group 4). Cerebral angiography showed funnelshaped widenings at the origins of the bilateral posterior communicating arteries. The maximum diameter of the widening was greater than 3 mm, so this widening was called an enlarged infundibular widening. Angiography showed a small bulge protruding posterolaterally from the wall of the right enlarged infundibular widening, and the right posterior communicating artery arose from the apex of the enlarged infundibular widening. Based on the findings of the brain CT and cerebral angiography, the diagnosis was SAH due to rupture of the right enlarged infundibular widening. Approximately 12 hours after the onset, the clot was evacuated through the right pterional approach. Bleeding from the small bulge of the right enlarged infundibular widening occurred intraoperatively, so a right-angled ring clip was applied parallel to the right internal carotid artery to obliterate the rupture point. Postoperatively, she was discharged without neurological deficit, and follow-up CT showed no other new infarction. We recommend clipping rather than wrapping or coating for similar cases of ruptured enlarged infundibular widening.
