Altered mental status, unspecified [R41.82], Reason for Study: ^Reason: assess progression of infarct History: multiple CVAs There is a 20 mm x 46 mm sized right cerebellar intraparenchymal hemorrhage with surrounding edema. Ventricle size appears to be slightly enlarged however, comparing to prior CT scan, no significant interval change since prior scan considering the difference of imaging modality.There are multifocal diffusion restriction lesions on the right hemisphere including right superior frontal gyrus, right internal capsule posterior limb, right thalamus indicating multifocal acute ischemic infarct. There is no evidence of hemorrhagic conversion on above acute ischemic infarct lesions.There is evidence of chronic ischemic infarct with encephalomalacia on the right occipital lobe.The sulci and cisterns are 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.
1. Intraparenchymal hemorrhage on the right cerebellar hemisphere with surrounding edema as described above.2. Multifocal scattered right hemispheric acute ischemic infarctions without evidence of hemorrhagic conversion.3. Chronic ischemic infarction with encephalomalacia, right occipital lobe.
