What is infundibulum in the brain

The infundibulum is hollow from inside, creating a space within it, called the infundibular recess.

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.

What is infundibulum in the brain

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. Louis , author, Origins of Neuroscience. This book shows a whole other side of how brains work by examining the most unusual behavior to emerge from the human brain. In it, you'll meet a woman who is afraid to take a shower because she fears her body will slip down the drain, a man who is convinced he is a cat, a woman who compulsively snacks on cigarette ashes, and many other unusual cases. As uncommon as they are, each of these cases has something important to teach us about everyday brain function. Through case studies of both exceptional people as well as those with disorders, Bizarre takes us on a fascinating journey in which we learn more about what is going on in our skull.

More examples of how medicine is art — the image below shows an ophthalmic artery aneurysm — not infundibulum, even though the ophthalmic artery origin is not on the side of what we decided is aneurysm, but the middle of it. As uncommon as they are, each of these cases has something important to teach us about everyday brain function. Because of how it is what is infundibulum in the brain in this location, this thing behaves like an aneurysm — meaning it has a risk of rupture, has irregular shape, etc.

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.

He insists this has no bearing on it and seems to think those are triggered only by stress. Should I get a second opinion? Any advice would be appreciated. Interested in more discussions like this? Hi lilcountry , welcome to Connect.
