What is infundibulum in the brain

An infundibulum is not an aneurysm, though it may look like one. We see a lot of patients who are told they have luulla aneurysm, but really have an infundibulum, or are specifically referred to us so that we can figure out which of the two they have.

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. Infundibular recess lies within the infundibulum. In fact, this recess is a tubular extension of the third ventricle into the infundibulum or pituitary stalk and contains cerebrospinal fluid. Tsutsumi, S. Clin Neuroradiol.

What is infundibulum in the brain

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. Only very rarely does an infundibulum eventually develop into an aneurysm 1 and it is generally not thought that an incidental infundibulum requires follow-up unless additional clinical concern is present. Prudent factors that may indicate follow-up include large size, family history of subarachnoid hemorrhage or aneurysm, connective tissue disorders or history of dissection, or an aneurysm elsewhere.

If the branch is too small to be seen, then deciding between aneurysm and infundibulum is not possible with certainty. Incoming Links.

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.

Dingman explores some of the most fascinating and mysterious expressions of human behavior in a style that is case study, dramatic novel, and introductory textbook all rolled into one. MRA relies on how water protons behave in strong magnetic fields. Notice also an infundibulum on the other end dashed arrow — a much less appreciated location.

MRA is especially better in children, childbearing age women, and others who should especially minimize exposure to radiation. An aneurysm is, most often, a kind of bubble located near or at origin of a vessel image on right. 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.
