A 50-year-old woman presented with a 10-year history of action dystonia involving her right leg. Neurological examination revealed only distal wasting of the right foot and pes cavus [Figure - 1]. Nerve conduction velocity, electromyographic studies, and video electroencephalography were normal. magnetic resonance imaging showed a large left parasagittal extraaxial mass lesion with surrounding subcortical edema [Figure - 2].
Muscle wasting due to upper motor neuron lesions is usually mild and attributed to disuse atrophy. Rarely, parietal lesions can cause a 'parietal wasting'.[1] Dystonia due to cortical lesions are also uncommon.[2],[3] In this case, the lesion location (over the leg motor cortex) suggested 'parietal wasting' and dystonia.
