 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 a persistent extra-axial fluid collection subjacent to the craniotomy flap. There is unchanged confluent T2 hyperintensity without associated mass effect within the left frontal white matter, in the region of the treatment bed. However, there is no enhancement in the region of 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 orbits and paranasal sinuses are unremarkable.
Unchanged postoperative findings without evidence of tumor progression.
