32-year-old male post resection of meningioma Post operative changes is post left temporal and frontal craniotomy again noted. Epidural fluid/air collection under the craniotomy flap as well as residual air in the subarachnoid space compatible with expected postoperative changes is stable in appearance. There is no evidence of intraparenchymal or extra-axial hemorrhage. Hypoattenuation in the anterior left temporal lobe adjacent to the surgical bed time, corresponding to area of restricted diffusion seen on prior MRI, is better defined on today's exam. Again noted minimal bulge of the left temporal lobe toward the basal cistern and left perimesencephalic cistern, stable.The appearance of ventricular system and the basal cisterns is unchanged compared to prior exam. There is no midline shift or hydrocephalus. Focus of high density above the left anterior clinoid corresponds to previously identified lytic or sclerotic left supraclinoid internal carotid artery, unchanged.Again noted cystic left cerebellar structure with CSF density, unchanged.The orbits are unremarkable. Left maxillary retention cysts are noted. Otherwise the visualized paranasal sinuses and mastoid air cells are well pneumatized.
1.Expected postoperative changes status post left frontal and temporal craniotomy as described above.2.Evolutionary change of left temporal lobe hypoattenuation corresponding to previously seen restricted diffusion compatible with infarct in left middle cerebral artery distribution.3.Unchanged posterior cranial fossa cyst.
