weakness There are multiple restricted diffusion lesions on the right right superior and middle frontal gyri indicating acute or subacute ischemic infarctions. Gyriform susceptibility artifacts on GRE within the restricted diffusion area indicate hemorrhagic conversion and corresponding enhancement on post Gad images suggest subacute ischemic infarction related blood brain barrier disruption.High signal intensity lesion on the left precentral gyrus hand motor cortex on DWI is likely to be T2 shine through. The ventricles, sulci and cisterns are symmetric and unremarkable. The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. The paranasal sinuses and mastoid air cells are clear.
Acute or subacute ischemic infarction on the right frontal lobe superior and middle frontal gyri with evidence of hemorrhagic transformation as described above.
