Intracranial sewing needles: Review of 13 cases.

Three new cases of intracranial sewing needles are reported and are reviewed with 10 other published cases. These needles must have been introduced in infancy before the closure of fontanelles. The intention, at least in most cases, has been infanticide. Except in one case which the mother reported and two cases found at necropsy, the others were diagnosed by skull radiography. Headache and epilepsy were the main symptoms and they often appeared when the patient had reached adulthood. Removal of the needles lessened the symptoms.
