Male, 70 years old, with history of grade 3 meningioma. Postoperative findings are again seen compatible with left parietal craniotomy and tumor resection. A thin layer of extra-axial fluid along the craniotomy is unchanged. T2 hyperintensity and hemosiderin staining within the underlying precentral and postcentral gyri are also unchanged. No evidence of recurrent tumor is seen in the operative bed.A nodular area of dural based masslike enhancement is seen centered on the paramedian high right vertex with involvement of the superior sagittal sinus (see image 131 series 1203). This lesion has increased mildly in size when compared to the prior examination. A tumor-like lesion was, however, evident in this location on exams which predated the most recent surgery. More anteriorly, non-tumoral bilateral dural thickening along the vertex is unchanged likely related to prior subdural collections. No new enhancing lesions are seen. No new areas of parenchymal signal abnormality are detected. Hemosiderin staining is redemonstrated along the bilateral frontal lobe surfaces, right more than left. No evidence of acute intracranial hemorrhage is seen. The ventricular system is within normal limits.
Postoperative findings are demonstrated compatible with tumor resection from the left high convexity. No definite progressive tumor is seen in this location.A separate nodule of probable tumor located along the right paramedian vertex with involvement of the superior sagittal sinus has increased slightly in size.No entirely new intracranial lesions are seen.
