Female, 66 years old, status post craniotomy for resection of meningioma. Evidence of repeat craniotomy at the high vertex is again seen. A resection cavity is present at the high convexity spanning the interhemispheric falx. The cavity contains a blood fluid level as expected for the immediate postoperative state.Tumor seen previously along the right aspect of the resection cavity has been significantly debulked. There is irregular enhancement along the right paramedian cavity which is nonspecific. Relatively thin enhancement along the left paramedian cavity is unchanged and favored to represent granulation tissue.Restricted diffusion is evident along the right resection cavity margin, particularly the floor of the cavity, which most likely represents postoperative sequelae. T2 hyperintensity compatible with vasogenic edema within both cerebral convexities shows no significant change from the prior examination.Evidence of prior left frontoparietal craniotomy is again seen with a stable resection cavity in the left middle frontal gyrus. A subcentimeter enhancing nodule along the left superior temporal gyrus is unchanged. Enhancement within the left squamous temporal bone is also unchanged.No new intracranial lesions are suspected. Ventricular size and morphology are unchanged.
Findings are seen compatible with re-resection of tumor along the right paramedian high convexity. Irregular but relatively thin enhancement along the right sided surgical margin is nonspecific and could represent postoperative change. Continued follow-up will be necessary to exclude the possibility of residual tumor. Relatively thin enhancement along the left paramedian resection cavity is unchanged and favored to represent postoperative granulation from prior surgery.
