Pituitary dwarfism: CT evaluation of the pituitary gland. 1986

Y Inoue, and Y Nemoto, and K Fujita, and H Aoki, and K Takemoto, and Y Tsukamoto, and J Oda, and Y Onoyama

The pituitary glands of 12 patients, aged 4-20 years, with pituitary dwarfism and of 15 age-matched control patients were evaluated with contrast-enhanced, high-resolution computed tomography (CT). In control patients, CT clearly demonstrated pituitary glands and stalks, 2.5-9.0 mm in height (average, 5.7 mm +/- 1.8). In the 12 patients with pituitary dwarfism, CT did not demonstrate the gland or stalk in four; CT faintly showed only the stalk in another four and showed a small gland (less than 2 mm in height) and a small to normal stalk in the remaining four. Eleven of the 12 patients had a birth history of breech presentation. Possible causes of pituitary dwarfism are discussed.

D010907 Pituitary Hormones Hormones secreted by the PITUITARY GLAND including those from the anterior lobe (adenohypophysis), the posterior lobe (neurohypophysis), and the ill-defined intermediate lobe. Structurally, they include small peptides, proteins, and glycoproteins. They are under the regulation of neural signals (NEUROTRANSMITTERS) or neuroendocrine signals (HYPOTHALAMIC HORMONES) from the hypothalamus as well as feedback from their targets such as ADRENAL CORTEX HORMONES; ANDROGENS; ESTROGENS.
