Abstract:
Van Wyk-Grumbach syndrome (VWGS) is a rare complication of prolonged untreated juvenile hypothyroidism characterized by precocious puberty and enlarged multicystic ovaries. A 13-year-old girl visited our outpatient clinic due to menstrual irregularities. She had precocious puberty, pituitary hyperplasia and multiple cystic ovaries in addition to clinical signs of severe congenital hypothyroidism. After the initiation of L-thyroxine therapy, the symptoms were alleviated in a short time. This rare syndrome is easy to be misdiagnosed as pituitary and ovarian tumor. High degree of suspicion and timely diagnosis can prevent unnecessary surgical procedures because the symptoms can be reversed with thyroid hormone supplementation.
