| hypothalamic obesity with hypogonadism | A disorder characterised primarily by obesity and hypogonadotrophic hypogonadism in adolescent boys; dwarfism is rare, and when present is thought to reflect hypothyroidism. Visual loss, behavioural abnormalities, and diabetes insipidus may occur. Frohlich's syndrome often is used synonymously for this disorder, although the original case involved a pituitary tumour; most cases are thought to result from hypothalamic dysfunction in areas regulating appetite and gonadal development. The most common causes are pituitary and hypothalamic neoplasms. Synonym: adiposis orchica, adiposogenital degeneration, adiposogenital dystrophy, adiposogenital syndrome, hypophysial syndrome, hypothalamic obesity with hypogonadism. Origin: L. Fr. G. Dys-, bad, + trophe, nourishment (05 Mar 2000) |

| hypothalamic sulcus | A groove in the lateral wall of the third ventricle on either side leading from the interventricular foramen to the aditus ad aqueductum cerebri; the sulcus-demarcated boundary between dorsal thalamus and hypothalamus. Synonym: sulcus hypothalamicus, Monro's sulcus. (05 Mar 2000) |
| dorsal hypothalamic region | The portion of the hypothalamus located immediately ventral to the hypothalamic sulcus; contains small nuclei, some of which are associated with the ansa lenticularis and the entopeduncular nucleus. (05 Mar 2000) |
| dorsomedial hypothalamic nucleus | An aggregation of cells in the middle hypothalamus dorsal to the ventromedial nucleus and bordering the third ventricle. (12 Dec 1998) |
| intermediate hypothalamic region | The infundibular portion of the hypothalamus, includes the medial tuberal nuclei and portions of the dorsomedial, ventromedial, arcuate (infundibular), posterior and lateral hypothalamic nuclei; located internally in the general area of the infundibulum. (05 Mar 2000) |
| lateral hypothalamic area | Extends throughout most of the rostrocaudal extent of the hypothalamus lateral to the column of the fornix; includes lateral tuberal nuclei, tuberomamillary nuclei, and diffuse populations of cells. Synonym: lateral hypothalamic area. (05 Mar 2000) |
