Headache. Status post tumor resection. There are postoperative findings related to left orbitofrontal craniotomy for resection of previously seen cystic and solid mass in the left inferior frontal lobe. Expected postsurgical changes include small amount of pneumocephalus and blood products within and surrounding the resection cavity. There is a small left sided extra-axial collection as well as small amount of subarachnoid hemorrhage. Surrounding vasogenic edema is again seen with FLAIR hyperintensity involving the left frontal corona radiata superiorly and extending inferiorly to the anterior temporal lobe. There is mild local mass effect with sulcal effacement. There is unchanged minimal rightward midline shift at the level of the inferior frontal lobes. Otherwise no large herniation. No hydrocephalus. There is restricted diffusion involving the left caudate head likely representing devitalized tissue. Restricted diffusion along the left anterior frontal lobe surface corresponds to blood products. There is no evidence of residual enhancement to suggest residual tumor.
1. Expected postsurgical changes related to resection of left frontal lobe mass. No evidence of residual enhancing tumor. There is persistent local mass effect and minimal rightward midline shift at the level of the inferior frontal lobes. 2. Diffusion restriction of the left caudate head, likely representing devitalized tissue.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
