Symptomatic osteolipoma of the tuber cinereum

The authors present a case of an ossified lipoma located at the tuber cinereum. Intracranial osteolipomas are rare lesions that occur in the region of the tuber cinereum. Almost all reported cases have been incidental autopsy findings. This report, however, involves a young girl who presented with an ovarian cyst and signs of precocious puberty, in whom a typical osteolipoma was surgically removed. This is the first case of hypothalamic osteolipoma presenting with endocrinological disturbances that has been published to date.
