What is infundibulum in the brain

The infundibulum is hollow from inside, creating a space within it, called the infundibular recess. Details suggest that the floor of the third ventricle or base of hypothalamus contains a raised area called tuber cinereum. This region has got the posterior pituitary or pars nervosa attached to it via a stalk called the infundibulum a.

AKA infundibulum or pituitary stalk, the infundibular stalk is a tube-like structure that connects the posterior pituitary to the hypothalamus. It allows for hormones synthesized in the hypothalamus to be sent to the posterior pituitary for release into the bloodstream. Know Your Brain: Pituitary Gland. Know Your Brain: Hypothalamus. We experience these things every day, but how do our brains create them? Your Brain, Explained is a personal tour around your gray matter. Dingman weaves classic studies with modern research into easily digestible sections, to provide an excellent primer on the rapidly advancing field of neuroscience.

An infundibulum is not an aneurysm, though it may look like one. We see a lot of patients who are told they have an aneurysm, but really have an infundibulum, or are specifically referred to us so that we can figure out which of the two they have. Most of the time, we can do that with CT or MR. Occasionally, a catheter angiogram is required. The picture above tells the story. An aneurysm is, most often, a kind of bubble located near or at origin of a vessel image on right. An infundibulum, on the other hand, is a wide base, like a pedestal, of a vessel image on left. In an aneurysm, the branch is located next to the aneurysm. In an infundibulum, the branch comes out of the top apex of the larger base. Of course, this is a simplification. Also, having an infundibulum does not protect one from having an aneurysm there also, so sometimes we see both at once. That is not common however. The most common vessel with an infundibulum is the posterior communicating artery PCOM — a branch of the internal carotid artery.

An infundibulum is not an aneurysm, though it may look like one. In an infundibulum, the branch comes out of the top apex of the larger base.

An infundibulum plural: infundibula is a conical outpouching from an artery usually intracranial , with a broad base narrowing to an apex from which a vessel originates. The most common location for an infundibulum is the origin of the posterior communicating artery PCOM from the supraclinoid internal carotid artery. They are common, found in up to a quarter of all cerebral angiograms 1. The main importance of an infundibulum is that it may be mistaken for a saccular berry aneurysm which is rounded and has the branch at its base. An infundibulum in most cases measures less than 3 mm. Unlike an aneurysm, an infundibulum is not believed to be a risk for rupture and subarachnoid hemorrhage.

If however it is important to know for sure if there is an aneurysm or infundibulum, a catheter angiogram may be done. This means that they can not see blood vessels below a certain size. The advantages of MRA are that it does not require x-rays or contrast. Citation, DOI, disclosures and article data. You can consent to the use of these technologies by clicking "accept all cookies".

MRAs are just like cars — old, new, bad, good, etc. The disadvantage used to be that it produced lesser quality images, and certain people with some metal implants could not have MRA. Loading more images Most of the time, we can do that with CT or MR. Edit article. The advantages of MRA are that it does not require x-rays or contrast. Bizarre is a collection of stories of how the brain can create zombies, cult members, extra limbs, instant musicians, and overnight accents, to name a few of the mind-scratching cases.

Good angiographic technique is important — in images below, the infundibulum looks like an aneurysm on the right image because of injection technique — the image on the left, with good technique, shows the PCOM branch arising from the apex of the infundibulum.
