A case of isolated hemithalamic overgrowth
The present case has been reported in Neurology. A 17-month-old boy reported with left hemiparesis, without any other neurologic disorder.

Brain MRI revealed a remarkable hypertrophy of the left thalamus. There were no differences with the right thalamus before and after using contrast, either a hypersignal in fluid-attenuated inversion recovery or restriction at diffusion-weighted imaging.

In the same way, the spectroscopy showed normal metabolite peaks (choline and N-acetylaspartate)1 (figure, A and B). This hemithalamus leaves a mark on the left anterior ventricle with a dilation of the opposite one that could explain the clinical sign.
