Hypothalamic hamaomas, also known as tuber cinereum hamaomas, are benign non-neoplastic heterotopias in the brain that typically occur in the region of the hypothalamus, arising from the tuber cinereum, a pa of the hypothalamus located between the mammillary bodies and the optic chiasm. The tuber cinerium and left mamillary body show a small solid mass lesion with isointense T1, slightly hyperintense T2 signal. The lesion shows no significant post-contrast enhancement. Hypothalamic hamaoma- do not enhance after contrast administration, if enhancement occur, always consider a glial tumour.
