 There are unchanged postoperative findings related to left parietal craniotomy for resection of a left frontal lobe mass with associated susceptibility effect in and adjacent to the resection cavity compatible with chronic blood products. There is an unchanged 11-mm thick CSF signal intensity extra-axial fluid collection subjacent to the craniotomy flap. There is unchanged T2 hyperintensity without associated mass effect within the left frontal white matter. There is no thick, nodular, or measurable enhancement near the resection cavity. There is no significantly elevated relative cerebral blood volume adjacent to the resection cavity. There is no evidence of acute infarct. The ventricles and basal cisterns are unchanged in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The paranasal sinuses are unremarkable.
Unchanged postoperative findings without evidence of tumor progression. I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
