Male, 33 years old, with history of epilepsy, status post left temporal lobectomy, surveillance imaging. Postoperative findings are seen compatible with resection of a portion of the left anterior temporal lobe. Previously seen acute postoperative findings including blood in the surgical cavity and extra-axial fluid have resolved. A small resection cavity remains showing thin rim enhancement which likely reflects postoperative granulation. T2 hyperintensity within the adjacent temporal parenchyma is seen perhaps representing gliosis or mild residual edema.Postoperative findings are also redemonstrated compatible with prior laser ablation of the left mesial temporal structures. A small amount of enhancement at the ablation site is unchanged. Elsewhere, parenchymal morphology and signal characteristics are within normal limits. No evidence of acute intracranial hemorrhage is seen. Ventricular size and morphology are within normal limits.
