We report pilomotor seizures in two patients who had piloerection or g
ooseflesh spreading in a pattern like the 'Jacksonian march', confined
ipsilaterally to the lesion side. The first patient presented this in
conjunction with complex partial seizures. Left anterior temporal lob
ectomy abolished pilomotor and other seizures. Pathological study demo
nstrated hippocampal sclerosis. A meningioma near the left sphenoid re
gion, incompletely removed, is the likely cause of pilomotor seizures
in the second patient. Carbamazepine reduced these attacks. To our kno
wledge, hippocampal sclerosis and meningioma have never been linked to
pilomotor seizures.
