Ea. Korn et al., THYROTROPIN-SECRETING ADENOMA IN AN ADOLESCENT GIRL WITHOUT INCREASEDSERUM THYROTROPIN-ALPHA, Hormone research, 42(3), 1994, pp. 120-123
A 13-year-old girl with poor weight gain and pubertal delay was referr
ed for hyperthyroidism. Slightly elevated levels of circulating thyroi
d hormones failed to suppress circulating thyrotropin (TSH) levels. De
spite appropriate thyrotropin-releasing hormone stimulation of TSH sec
retion, a thyrotropin-secreting pituitary adenoma was identified as th
e cause of inappropriate TSH secretion.
