title: Report of changing signal intensity on follow-up MRI in a case of hypothalamic hamartoma.
abstract: We present a case of hypothalamic hamartoma in which the signal intensity of the lesion significantly changed during the course of follow-up. To date, stability of the lesion morphology over time has been considered an important diagnostic criterion of hypothalamic hamartoma. Radiologists should be aware that in hypothalamic hamartoma, signal intensity can change during its natural course.
