 Again seen are postoperative changes related to resection of two right parietal meningiomas. Compared to 6/26/2015, there is been decrease in size of the resection cavity in the right paramedian parietal region. More inferiorly irregular areas of enhancement in the right parieto-occipital region and are not significantly changed. Unchanged nodular areas of enhancement along the right parietal convexity. No new or enlarging mass is seen to suggest tumor recurrence. Minimal parieto-occipital extra-axial collection is again seen. Chronic segmental occlusion of the posterior superior sagittal sinus is again seen with patency more anteriorly and posteriorly.The T2/FLAIR signal abnormality within the brain parenchyma surrounding all of these areas is similar to prior study. The remaining brain parenchyma is otherwise unremarkable. There are no other intracranial lesions identified.
Compared to 6/26/2015, there is evolution of postsurgical changes related to resection of two right parietal meningiomas. Minimal areas of nodular dural thickening and enhancement in the right parieto-occipital region have not significantly changed. No findings to definitively suggest tumor recurrence.
