 Again seen are postoperative findings related to a right posterior parietal craniotomy. The resection cavity is unchanged with mild T2/FLAIR signal surrounding the CSF-filled cavity remaining unchanged across multiple prior studies. There are no areas of pathologic enhancement. Curvilinear susceptibility abnormality along the lateral aspect of the right frontal lobe and within the central sulcus/post central gyrus, likely reflects chronic blood products and is unchanged. Incidentally seen is a small arachnoid cyst without mass effect along the left frontotemporal operculum and also remains unchanged. The ventricles are within normal limits and the basal cisterns remain patent. No areas of diffusion restriction are present to suggest an acute ischemic event. No extra-axial fluid collection is identified. The cerebellar tonsils are in normal position. Pituitary gland is unremarkable for age. Normal flow-voids are demonstrated in the major intracranial vascular structures. The midline structures and craniocervical junction are within normal limits. Left maxillary sinus mucous retention cyst. The orbits are unremarkable.
Posttreatment changes in the right parietal lobe. No evidence of tumor recurrence.
