Here we present a very rare case of a woman with a bone fragment in the third ventricle of the brain following compound-depressed skull fractures due to a road traffic accident. There are only few case reports of bullets and textiloma being removed from the third ventricle. Following operative removal of the fragment, the patient was started on cortisol, mineralocorticoid and thyroid hormone replacement. However, the patient eventually died of the severe traumatic hypothalamic insult.
