A hypothalamic or tuber cinereum hamartoma is benign non neoplastic heterotrophic lesion in the brain that typically occurs about the hypothalamus. The tuber cinereum is a part of the hypothalamus located between the mamillary bodies and the optic chiasm. Thought to arise from anomalous neural migration between 35 and 40 days in utero (time of hypothalamic formation). This is isointense to gray matter on T1 weighted images and hyperintense on T2 and FLAIR images. There was no post gadolinium enhacement. This is 28year old male.
