We report the case of a 2-year-old child who sustained a permanent diabetes
insipidus following a third ventriculostomy for hydrocephalus from a Dandy

drocephalus, can cause complications such as diabetes insipidus. The latter
has rarely been reported and is usually transient. Following ventriculosto
my, a close postoperative surveillance is essential, especially in children
