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 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.

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.

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. 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.

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?

The pituitary stalk, also known as the infundibulum or infundibular stalk , is largely outside the blood brain barrier like the rest of the pituitary and therefore normally enhances following the administration of gadolinium. It gradually tapers inferiorly, and superiorly is spread by the infundibular recess of the third ventricle. There have been some studies looking at the range of normal sizes of the pituitary stalk. One study 2 had a normal range of:.
