Partial epileptic seizures beginning in the truncal muscles.

3 patients suffered from partial epileptic seizures beginning in truncal muscles on one side. A gross anatomical lesion was demonstrated in the contralateral parietal area in 2. In the third patient, both interictal and ictal EEG features were consistent with an epileptogenic lesion in the similar location. Several factors seem to contribute to the rarity of this variety of partial seizures.
