Abstract:
The clinical data of a child with Van Wyk-Grumbach syndrome (VWGS) who visited Capital Institute of Pediatrics in 2019 were retrospectively analyzed. The patient was a seven year old girl, her main clinical manifestations included short stature (well below -2 standard deviations), obesity and breast development. The results of laboratory testing indicated that the level of thyrotropin (TSH)>100 mIU/L and the level of free thyroxine (FT 4) was 5.15 pmmol/L; serum estradiol and prolactin levels were significantly elevated; the gonadotropin-releasing hormone(GnRH) stimulation test showed that the gonad axis was not activated. She had giant ovarian cyst, pituitary hyperplasia, anemia and pericardial effusion. Bone age was delayed; and her blood lipids had increased. Therefore, she was diagnosed as Van Wyk-Grumbach syndrome. The patient received the treatment of levothyroxine, the drug does was gradually increased from 25 μg per day to 75 μg per day, vaginal bleeding was followed by medication for 3 days. Three months later, her thyroid function was back to normal, and giant ovarian cyst regressed, but the ovaries were bulky,pericardial effusion was absorbed. The levothyroxine dose was adjusted to 50 μg per day according to the test result of thyroid function. And 1 year late the thyroid function was normal, pituitary magnetic resonance imaging(MRI) showed the hyperplastic adenohypophysis was back to normal, no more vaginal bleeding occurred, and the giant ovarian cyst was shrunk.
