An unusual case of penetrating brain injury by pruning shears is reported. CT scan on admission showed subarachnoid and intraventricular hemorrhage, and intraserebral hematoma. Autophy revealed that these hemorrhages were caused by penetration of the shears. The penetrating fracture at the frontal skull base could not be diagnosed by plain radiography or CT scan. Ashas been stressed previously, we recommend that foreign bodies which have penetrated the head syould not be removed at the site of the accident.
