Imaging in Van Wyk Grumbach syndrome: An uncommon presentation of hypothyroidism

Isosexual precocious puberty with ovarian masses in long-standing juvenile hypothyroidism is well described in the literature as Van Wyk Grumbach syndrome (VWGS). The present case reports this rare entity in a 4-year-old girl who was referred for imaging to evaluate the cause of non-traumatic bleeding per vagina. Antecedent history, clinical features and thyroid function tests were consistent with long-standing juvenile hypothyroidism with documented clinical response to thyroxine replacement therapy.
