Frohlich's adiposogenital syndrome
Frohlich's adiposogenital syndrome is a rare endocrine disease of dogs associated with hypothalamic disease due to a mass-effect within the sella turcica due to pituitary adenomas, pituitary adenocarcinomas, infundibulomas or craniopharyngiomas.
Secondary diabetes insipidus may also be observed.
A tentative diagnosis can be established by imaging (usually MRI) which may reveal a pituitary mass. Blood test may show abnormally low GnRH, LH and testosterone blood levels. Definitive diagnosis requires fine-needle biopsy of pituitary or exploratory craniotomy.
Treatment usually requires hypophysectomy.
Physical signs usually resolve following surgery, although diagnosis is usually made in late stages of disease, and prognosis may be guarded in such cases.
