A 13-year-old girl with poor weight gain and pubertal delay was referred for hyperthyroidism. Slightly elevated levels of circulating thyroid hormones failed to suppress circulating thyrotropin (TSH) levels. Despite appropriate thyrotropin-releasing hormone stimulation of TSH secretion, a thyrotropin-secreting pituitary adenoma was identified as the cause of inappropriate TSH secretion.
