Fig. 2. Control MRI: there is a hyperintensive signal from an embolizing substance and an ischemic focus, spreading forward from the anterior horn of the left lateral ventricle, on tomograms in axial (a) (T2-WEIGHTED) and coronary (b) (T1- WEIGHTED) planes. MR-angiography in a TOF mode and lateral (c) and direct (d) projections is indicative of absence of a signal from ACA, being the largest afferent vessel of AVM, and reduction of an AVM knot volume. Patency of the left MCA in a bifurcation area is not impaired.
