Reason: Generalized Tonic Clonic Seizures History: Generalized Tonic Clonic Seizures Susceptibility artifact limits evaluation of the right cerebellum on DWI and susceptibility weighted images.There is no evidence of intracranial hemorrhage, mass, or acute infarct. Focal prominence of the extra-axial space along the left cerebellum with mild mass effect may represent a minimal retrocerebellar cyst or mega cisterna magna. The brain parenchyma and pituitary gland appear unremarkable. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact.
1.No underlying structural abnormalities to explain patient's seizures.2.Focal prominence of the extra-axial space along the left cerebellum may represent a minimal retrocerebellar cyst or mega cisterna magna.
