Male, 4 years old, with history of generalized tonic-clonic seizure in 7/2016, recurrent on two other occasions and on current admission. No evidence of parenchymal edema, mass effect or restricted diffusion is seen. No structural defects are identified. Slight asymmetric prominence of the right temporal horn is seen. The mesial temporal structures are normally formed, symmetric and free of abnormal signal intensity. No evidence of intracranial hemorrhage or any abnormal extra-axial collection is seen. Ventricular size and morphology are otherwise within normal limits.
Slight asymmetric prominence of the right temporal horn may represent a developmental variant. The mesial temporal structures are otherwise unremarkable. No specific findings are seen which would account for the patient's seizures.
