Altered mental status, unspecified [R41.82], Reason for Study: ^Reason: Evaluate for mass, strokes History: altered mental status. Multiple scattered restricted diffusion lesions on the left occipital lobe without evidence of hemorrhagic transformation nor evident surrounding edema indicating subacute or early chronic ischemic stroke. The lesions are seen as subtle high signal intensity lesions on FLAIR images.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. 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. Multiple retention cysts on bilateral maxillary sinuses and opacifications on bilateral ethmoid sinuses, sphenoid sinus and frontal sinus.
1. Subacute or early chronic ischemic infarctions at the left occipital lobe, likely left PCA territory without evidence of associated hemorrhagic transformation nor surrounding edema.2. Otherwise unremarkable.
