Abstract
- The authors report a case of a 16-year-old girl with pituitary hyperplasia and primary hypothyroidism caused by Hashimoto's thyroiditis. She presented with growth arrest, and hormonal studies showed decreased level of free thyroxine (T4), and increased levels of thyroid-stimulating hormone (TSH) and prolactin. A pituitary magnetic resonance imaging (MRI) showed a suprasellar mass. After 2 months of thyroxine replacement, thyroid function and high prolactin levels normalized, and the pituitary hyperplasia disappeared. This case represents relatively rapid normalization of pituitary hyperplasia, compare to the previous studies.
