The arrow-head which went through the brain

An 18-year old man was admitted into hospital being fully conscious, with a thirteen centimetre long metal arrow-head entirely lodged intracranially, having entered through the right orbit. Pre- and post-operative neurological condition, treatment and investigations are described. The arrow-head was removed through a partial occipital craniectomy without any major haemorrhage. The patient not only survived the operation, but was also discharged in an astonishing improved neurological condition.
