No clue what this means, that is what your non functional doctor is for.

We
describe a case of brain cortical reorganization after embolization of a
large right temporal arteriovenous malformation. A comprehensive
imaging protocol, including functional magnetic resonance imaging
(fMRI), cortical thickness analysis and 320-row computed tomography (CT)
perfusion was used to provide information on brain plasticity and
potential steal phenomenon. A 25-year-old man known for a right temporal
grade V Spetzler-Martin classification arteriovenous malformation (AVM)
presented with left progressive hemiparesis. He underwent functional 3T
magnetic resonance imaging (fMRI), cortical thickness analysis, and CT
perfusion (CT 320 row, Aquilion ONE, Toshiba, Tokyo, Japan) before and
after endovascular treatment.
The results were compared to look for modifications in brain perfusion and organization. An improvement in the left hemiparesis and a reorganization of motor function were observed after endovascular treatment. Modifications in the angioarchitecture and perfusion of an extensive AVM may be accompanied by a functional and structural reorganization of the brain. The location in the so-called eloquent regions may not be sufficient to explain the wide spectrum of symptoms that these patients can present. A more comprehensive approach considering a global involvement of the brain in patients with large AVMs is suggested to achieve the best treatment strategy and to stage treatment in incurable AVMs.

This one is like mine. Large bleeding mass in an eloquent location...rendering "atypical" symptoms for location. That was part of the problem in getting any md to figure out my case. The symptoms didn't match the location....so much for brain mapping. My guess is that the mass effect was creating some of the symptoms.
