Hi, Tom ~
Thanks for sharing your AN experience with us although I'm sorry to learn that your initial debulking surgery and irradiation were not completely successful.
My debulking & radiation experience was quite different. At age 63, I was diagnosed with a large AN, pressing hard on my brain stem. My AN-experienced neurosurgeon (30 years) decided (with my agreement) to debulk then radiate the AN in order to spare my facial nerves, a major concern of mine. The 4.5 cm tumor had it's blood supply severed and was surgically reduced to approximately 2.5 cm using the Retrosigmoid approach. The remaining tumor folded in on itself, as expected, making it susceptible to the effects of radiation. I enjoyed a relatively rapid recovery and the follow-up radiation (FSR - 26 sessions, 3 months later) was uneventful. Subsequent MRI scans revealed the remaining tumor showing definite necrosis and the beginnings of shrinkage. My pre-op symptoms (severe imbalance, loss of taste and appetite, fatigue) disappeared immediately following the surgery and I was blessed to have no post-op complications, facial nerve issues or otherwise. That was 7 years ago (June, 2006) and to date, I've had no AN-related problems. Proving that every AN patient and case is unique and one patient's experience does not necessarily serve to predict another patients experience, whether good or not so good.
I hope that your current issues will be resolved soon. Our membership appreciates every AN patient's experience and we're here to support you as only folks who've been through AN surgery and/or radiation, can. Please consider this website a resource.
