Regression of stroke-like lesions in MELAS-syndrome after seizure control Volume 12, numéro 4, December 2010

Figure 1 EEG recordings showing intermittent sharp waves over the left fronto-temporal projections.

Figure 2 Coronary TIRM-sequence, showing slight inner atrophy of the left temporo-parietal region at age 33 years (left). An axial T1-sequence of the same investigation shows gyral enhancement in the left temporo-occipital region (right).

Figure 3 TIRM-sequences, showing normal basal ganglia (left) and hyperintense heads of the caudate nucleus (right).

Figure 4 Axial T2-weighted MRI at 35 years old in the described patient showing a left temporo-parieto-occipital hyperintensity, being interpreted as a stroke-like lesion (left). This lesion had disappeared within one year after having become seizure-free at 37 years (right).
