Unusual penetrating craniocerebral injuries. Report of three cases.

Three cases of penetrating cranio-cerebral injuries are reported. Two were caused by steel hooks shot by rotating blades: in one of these, the foreign body penetrated the brain through the eye-ball and in the second case the main injury was caused by a careless of extraction. In the third case, the foreign body, a key, penetrated the left parasagittal rolandic area following an under-water injury. All three patients were submitted to surgery and had good neurological recovery without complications of infection or seizures.
