I have been diagnosed with a 2mm. infundibulum, the Neurologist told me it's different than aneurysm. May the infundibulum be treated? I don't have headaches, but I'm very anxious person, I will have a new CTSC and MRI at the beginning of 2021 the Neurologist will check how it's going.

Hi @mirthy21, welcome to Mayo Clinic Connect. I can understand your concern.

The pituitary gland, located at the base of the brain, is connected to the hypothalamus by a small stem called the infundibulum (or pituitary stalk). Infundibular dilatations (IFDs) are conical, funnel-shaped pouches at the origin of cerebral arteries, and can be difficult to distinguish from an aneurysm. According to this journal article, "the dilatation should be considered as a possible aneurysm only when it measures more than 3 mm in diameter." https://pdfs.semanticscholar.org/6b3b/ce7eae2263f123756c1fd3b27cf087d64abe.pdf

I moved your question about whether an infundibulum can be treated to this existing discussion where members like @kimbo @angie4 @kariulrich @lilcountry @kmaureenc21 @hopeful33250 and talking about options.

It sounds like your neurologist is actively monitoring the infundibulum for the time being. Were any treatment approaches discussed?
