Hi! Thanks for reading. My 12yo daughter was diagnosed with a bout of lab last July following an upper-respiratory virus. Spinning episodes continued, so we went to ENT which did VRG which showed some sort of issue, but inconclusive as to next steps...thought might be MAV. Went to neuro who diagnosed migraines, but now wants to do MRI to get to bottom of residual dizziness.
Is an MRI indicated? Can a bout of lab trigger MAV? Just asking. We're doctor-weary.
I did some quick research, and have found documented cases of people who have suffered from both Labs and MAV. However, I do not know if there is any real connection between the two.
Since the neurologist has diagnosed MAV, I would continue treatment for MAV.
However, if your daughter does not achieve any relief from the MAV treatment, I would consider visiting another ENT and have another ENG performed.
Have you considered the possibility of BPPV? This commonly follows cases of Labs.
Thanks for the research. I appreciate it. We will certainly continue treatment for MAV. The ENT, I believe, is hedging his bets on the current dizziness on that condition (MAV), thinking that the original labs have settled. I did ask him about BPPV and he thought not.
I'm curious to know, though, whether a MRI is indicated since it can't do much to diagnose either condition (or so I'm told). This is a high-volume (but very reputable) neuro group, but I wonder if the MRI is a rule out or a rule in?
I am guessing that since the doctors have not made any absolute conclusions, the MRI is probably just to rule out the possibility of a tumor. This problem is very rare, but it does sometimes cause vertigo. However, no need to worry about this because it is very unlikely!

First let me say how sorry I am that your daughter is experiencing this. I'm a mom too and I know how hard it is to watch our kids go through difficult things. I just wanted to add my experience in hopes it might help some. The MRI is fairly typical with these symptoms. It's to rule out tumors or other abnormalities. As ichbindarren said, its very unlikely so I wouldn't worry about it too much. I had Vestibular Neuritis (VN) about 15 mos ago--its similar to labs but doesn't involve any hearing loss. After the VN, it definitely kickstarted other things such as TMJ, BPPV and one neurotologist thinks migraine. They really don't know...they're professional guessers. The one thing I do know is that VN and labs can stir up other issues.
I will pray that your daughter will find relief from her symptoms soon.
