Hypothyroidism presenting with development delay, failure to thrive, and pituitary adenoma
Keywords:Congenital hypothyroidism, Pituitary adenoma
Pituitary enlargement secondary to primary hypothyroidism (PH) is a known but uncommon occurrence, and is also difficult to distinguish on CT and MRI from primary pituitary tumors. Following adequate hormone replacement with L-thyroxine, both symptoms and pituitary hyperplasia are reported to regress within a few months. It is important to recognize this condition so as to avoid unnecessary surgery.
