Hypothalamic hamartoma associated with a craniopharyngeal canal.

Abstract

Hypothalamic hamartoma is a rare congenital lesion. We present the case of a 7-year-old girl who suffered from precocious puberty, the cause of which was diagnosed by using MR imaging and CT as pedunculated hypothalamic hamartoma associated with a large craniopharyngeal canal and sellar spine mimicking pituitary duplication.
