Pilomotor epilepsy.

The case is reported of a patient presenting pilomotor seizures as the initial symptom of a tumour of the deep temporal lobe. Six other cases had previously been reported with the same type of seizures. The responsible lesion was often a tumour in deep temporal lobe and the distribution of the piloerection attacks was almost always ipsilateral. Pilomotor seizures deserve a definite role in the nosography of partial epilepsy.
