I have just had a CTA scan that detected a aneurysm at the left side of the base of my skull and a bulge or mass on the right. This was a follow up to an ER visit where I had a CT scan, an MRI, an MRA and a spinal that didn t show an aneurysm. The referral the the neurologist and the order of the MRA identified the aneurysm, explaining my symptoms and field trip for 14 hours in the ER, etc. I don t think my aneurysm has ruptured. The neurologist mentioned a coiling procedure but hasn t called back with neurosurgeon appointment date yer. What should I expect as next steps? Is this critical? I feel ok during the day but very uncomfortable when i lay down with an awful headache.
