The brain MRI images.. (a) Brain MRI after three years after the onset of headache and two years after the onset of partial seizures reveals atrophy of the left frontal temporal lobe and deep gray matter, with large patchy abnormalities on T1 and T2 sequences with bilateral ventricular enlargement.. (b) Brain MRI after five years after the onset of headache and four years after the onset of focal seizures shows atrophy of the left cerebral hemisphere, with this space occupied by T1 and T2 signal lesions with enlargement of the third and fourth ventricles and left ventricle.

Three years after the onset of headache, brain MRI (Fig. 1a) showed atrophy of the left frontal temporal lobe and deep gray matter, large patchy hypointensities on T1 and increased T2 signals, and bilateral ventricular enlargement. Brain MRI (Fig. 1b) revealed atrophy of the left cerebral hemisphere, with this space occupied by abnormal T1 and T2 signals, as well as enlargement of the third and fourth ventricles and the left ventricle.
