Status post craniotomy for seizure focus resection. Evaluate for hemorrhage and resection. There are postoperative findings related to a left craniotomy for resection of seizure focus. There is overlying soft tissue swelling, blood products along the resection cavity, and left frontal convexity and small extra-axial collection in the left hemisphere measuring 7mm in width. There is associated diffusion restriction and susceptibility artifact along the resection cavity, likely related to hemorrhage and ischemia. There is minimal left to right midline shift of 2 mm. There remains a focal area of prominent cortical thickening in the depths of a left posterior frontal lobe middle frontal sulcus. The ventricles and basal cisterns are unchanged in size and configuration. There is no herniation. There is fluid signal in the mastoid air cells.
Postoperative findings related to resection of seizure focus with apparent residual area cortical dysplasia in the depths of a left posterior frontal lobe middle frontal sulcus with superimposed edema. I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
