Cerebral infarction, unspecified [I63.9], Reason for Study: ^Reason: please rule out acute on chronic brain infarct History: presenting with acute on chronic right sided weakness There are scattered restricted diffusion areas on the left precentral gyrus indicating acute ischemic infarct. There is no evidence of hemorrhagic conversion.The ventricles, sulci and cisterns are symmetric and unremarkable. There is no mass, mass effect, edema, midline shift, intra or extra-axial fluid collection/hemorrhage, or restricted diffusion/acute ischemia. The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. The mastoid air cells are clear.Retention cyst on the left maxillary sinus.
Acute ischemic infarct on the left precentral gyrus without hemorrhagic transformation as described above.
