 Again seen are postoperative findings related to a right posterior parietal craniotomy. The resection cavity is unchanged with stable mild T2/FLAIR signal surrounding the CSF-filled cavity. 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 old blood product and is unchanged.The ventricles and sulci 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. 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.
1. Compared to most recent prior from 3/27/2015 and more remote priors dating back to 10/4/2013, there is no significant interval change in appearance of the right posterior parietal resection cavity with small areas of surrounding FLAIR hyperintensity without enhancement. No evidence of tumor recurrence. 2. Stable small focus of chronic hemosiderin deposition in the right central sulcus/post central gyrus.
