Other specified disorders of muscle [M62.89], Reason for Study: ^Reason: eval for stroke History: R sided weakness Brain MRIMultifocal bihemispheric subcortical gyriform diffusion restrictions on bilateral basal ganglia, bilateral MCAs', bilateral PCAs' territory and bilateral cerebellar hemispheres indicating acute/subacute ischemic infarctions. Gyriform subcortical T1 high signal intensity lesions demonstrate laminar necrosis. There are multifocal nodular susceptibility lesions within restricted diffusion lesions suggesting hemorrhagic transformations.The ventricles, sulci and cisterns are symmetric and unremarkable. The gray-white matter differentiation is normal. The midline structures and cranial-cervical junction are normal. The paranasal sinuses are clear.Bilateral mastoid air cells show fluid collections.Brain MRA3D time of flight MOTSA MRA brain images with maximum intensity projections of the anterior/posterior intracranial circulation demonstrate normal ICAs, MCAs and ACAs. The right PCA is fetal origin and the right ACA A1 segment is hypoplastic. Vertebrobasilar system appears to be normal.
Bihemispheric, supra and infra tentorial mainly subcortical most likely subacute ischemic infarctions with hemorrhagic transformation without evidence of focal indicate possible global hypoxia instead of embolic origin.
