Among these patients, those whose values were below 10 mteg/ml, showed no clini...
متن کاملPosterior pituitary ectopia: an MR feature of pituitary dwarfism.
Using high-field-strength, 1.5-T, high-resolution MR, we identified the following complex of neurohypophyseal abnormalities in each of five pituitary dwarfs: (1) severe hypoplasia or total absence of the infundibulum; (2) absence of the posterior pituitary bright spot in its normal location; and (3) a 3-8-mm tissue nodule at the median eminence exhibiting lipidlike signal on T1-weighted images....
متن کاملOptic hypoplasia with pituitary dwarfism (Kaplan-Grumbach-Hoyt syndrome, or DeMorsier syndrome).

متن کاملHypothalamic-pituitary functions in patients with idiopathic pituitary dwarfism.
To investigate hypothalamic-pituitary functions and the primary site of the lesion in idiopathic pituitary dwarfism, various pituitary function tests, especially the pituitary hormone responses to the hypophysiotropic hormones were studied in 23 patients with idiopathic pituitary dwarfism. A few cases showed slight responses of GH to GH stimulation tests. Gonadotropin deficiencies were most fre...
