case_images: MRI of the brain. Narrowing of the subarachnoid space. A pathological increase in the intensity of the signal by T2/TIRM and DWI from the cortex of the brain substance is determined, the change in the signal is symmetrical from the basal nuclei with their hemorrhagic transformation. Symmetrically increased T2/TIRM signal from the medial thalamus, periaqueductal gray matter

case_images: The pathological process mainly affected small vessels with varying degrees of segmental and total destruction of the endothelium, its swelling, desquamation, fibrinoid necrosis of the walls and pronounced perivascular edema (Fig. 2a-c).
