14 year-old history of complex partial epilepsy secondary to cortical dysplasia and ganglioglioma status post surgical intervention. Additional history of ganglioglioma resection in 2011. Post surgical changes from resection of the left temporal and occipital lobes. There is also encephalomalacia involving the mesial left parietal lobe with adjacent white matter gliosis presumably postsurgical in etiology. There is ex vacuo dilatation of the left lateral ventricle as well as 3 mm leftward midline shift.No abnormal enhancement on the postcontrast images. No areas of cortical dysplasia are identified. The expected intracranial vascular flow voids are present.Left maxillary sinus mucous retention cyst. There is partial opacification of the left mastoid air cells. The orbits are unremarkable.
1. Expected post surgical changes from left parietal, occipital and temporal resection for management of refractory epilepsy. No unexpected structural abnormality or enhancing mass is identified.2. Left maxillary sinus mucous retention cyst.
