 There are findings related to left temporal craniotomy, including fluid and swelling of the overlying scalp and periorbital tissues. There has been interval resection of previously demonstrated cavernous malformation in the left temporal lobe. There is an area of intrinsic high T1 signal intensity and corresponding susceptibility effect in the resection bed in the left temporal lobe consistent with hemorrhage. There are also residual areas of curvilinear susceptibility effect along the margins of the resection cavity that correspond to preoperative hemosiderin deposits. There is no evidence of acute territorial infarction. The ventricles and sulci are within normal limits in size and configuration. There is no midline shift.
Status post recent gross total resection of a left temporal lobe cavernous malformation with residual areas of hemosiderin staining along the periphery of the resection cavity. I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
