title: Histiocytosis-X of the hypothalamus.
abstract: Hypothalamic masses associated with histiocytosis-X may be mistaken for neoplasms. As a result radiation therapy will often be administered rather than chemotherapy, which appears to be the treatment of choice for histiocytosis-X of the hypothalamus. Particularly in young people, the possibility of granulomatous disease should be entertained and biopsy should be considered in the presence of a hypothalamic mass.
