Late post/update here. Just off phone with Stephanie. Scott went for a combination MRI/MRV after the CT. Turns out Steph's persistence (I just helped on the phone during a discussion) with Doctor Obzut about going ahead with the MRI after a clear CT paid off. Doctor O has actually thanked Stephanie for pushing her to go ahead, as the imaging discovered the source of Scott's odd behavior (and maybe even this whole hospital stay - that's arguable). Doc O admitted it wasn't really the direction she would have went.
Scott has a "partially occluded" blood vessel in his head. Basically a blood clot, but it's not completely blocked the specific vein. The treatment will begin with blood thinners (similar to warfarin) injected, yes, into his belly. They are the subcutaneous type, not the deep tissue type. Which basically means the nurses say the needles aren't that big.
While knowing your child has a partial clot in his head is certainly nothing to celebrate, at least we now know what in the world to actually deal with and treat, and the treatment is beginning as we speak. We THINK it will be a pair of injections twice a day. We'll never fault Doc O for that not being her intended direction. This cancer mess has so many twists and turns, it hard to imagine.
I do want to clarify something - this doesn't mean Scott has had a stroke. It means something has been found that needs to be corrected as if it completely blocked, that is the definition of a stroke (I will verify the accuracy of that with neurology in the morning).
Anyway, everything treatment-wise will be detailed out with morning rounds with doctors.
I love my "hovering mother" (as Doc Messina called her) of a wife. An object lesson in being your child's advocate and voice.
I think they're may be a graveyard shift radiologist that needs a huge thank you as well.
