Diagnosis: Epilepsy, unspecified, not intractable, without status epilepticusClinical question: seizuresSigns and Symptoms: seizures The CSF spaces are appropriate for the patient's stated age with no midline shift. A previously noted T2 hyperintense lesion in the splenium of the corpus callosum is significantly less conspicuous on the current exam.There are burr holes present along the left temporal bone and the left parietal bone. Since the prior exam depth electrodes have been removed. There are tracts of T2 signal hyperintensity within the parenchyma of the left temporal and parietal lobe where the depth electrode was placed. Tracts associated with the previously placed electrodes along the left insular cortex are not as readily appreciated.Normal vascular flow voids are present in the distal carotid and vertebral arteries, the basilar artery and the proximal anterior, middle and posterior cerebral arteries as well as the internal cerebral veins and superior sagittal sinus. The right vertebral artery appears hypoplastic distally.The visualized portions of the paranasal sinuses are clear. The visualized portions of the mastoid air cells are clear. The visualized portions of the orbits are intact.
1.Status post removal of the electrodes with posttreatment change.2.Please note that this is a limited exam performed for guidance during treatment.3.There has been interval partial resolution of a splenium of corpus callosum lesion.
