    Abstract:
    Primary empty sella syndrome (ESS) is an anatomo-radiological picture characterized by the presence of an arachnoid herniation filled with liquor that compresses the pituitary against the sellar wall. ESS occurs particularly in obese, hypertensive, cephalgic women, it is often asymptomatic but it may be associated with ophthalmologic, neurologic and sometime non-characterizing endocrine disorders. We report here 71 cases of primary ESS observed and assessed during the last fourteen years. The following endocrinological diagnostic procedures were carried out: hormonal (RIA) basal profile: FT3, FT4, TSH, PRL, ACTH, FSH, LH, 8.00 a.m. and p.m. cortisolemia, Aldo, PRA, DHEA-S, FTe, E2, P, PTH, CT, and calcemia and phosphoremia; provocative tests: TRH, GnRH, insulin hypoglycemia, etc.; inhibition tests: "overnight" and high dose dexamethasone. Clinical, radiological (skull radiographs, CT and/or MRI) and ophthalmologic (fundus, visual fields) assessment were made. We found principally cephalgia (52/71: 73.2%), hypertension (42/71: 59.1%), obesity (47/71: 66.1%). But we found especially mental disorders (57/71: 80.2%), in our knowledge not previously reported in the literature, as anxiety or dysthymic disorders with behavioural disturbances (chiefly oral compulsion). We found endocrinopathies in 36/71 (50.7%), isolated or coexisting in some patients: hyperPRL (14%), hypopituitarism (10.4%), hypogonadism (7%), diabetes insipidus (2.8%), hyperACTH (1.4%), hypoGH (15.4%), pituitary adenomas (8.4%). Several hypothalamic illness show a clinical picture including mental disorders and obesity. The Authors hypothesize that the ESS may be a "new" hypothalamic syndrome (compression/stretching on hypophysis and/or hypophyseal stalk by arachnoidocele; disorder of some hormones and neurotransmitters as leptin, neuropeptide Y, orexins, POMC-derived peptides, etc).
