I had a sudden onset of headaches and pressure around my left eye. I brought this up at an already scheduled annual exam. My doctor recommended I have an MRI/MRA. The findings were: Head MRA: 4 mm left internal carotid artery ophthalmic segment
saccular aneurysm. Brain MRI: Normal.
From this, I met with the neurology department and completed a CT with dye. Their findings were: Redundant left ophthalmic artery infundibular origin versus small aneurysm. Catheter angiography would be helpful for more definitive characterization.
I am planning on having my Angiogram on Friday to hopefully help determine whether this is an aneurysm or not. In the mean time, I also just found out that my sister had an MRA and her findings were that she has either a small aneurysm or infundibulum nearest the carotid artery.
My questions are: can an infundibulum lead to an aneurysm and are infundibula genetic or hereditary?
Thanks in advance!
