Abstract

Primary hypothyroidism can result in reactive enlargement of the pituitary gland which is indistinguishable from primary pituitary lesions in clinical presentation and on magnetic resonance imaging. A 17-year-old girl came to the hospital due to short stature, general weakness and galac-torrhea. The magnetic resonance imaging (MRI) study showed pitutary enlargement. The hormone study showed hyperprolactinemia, decreased basal growth hormone level and primary hypothyroi-dism. By thyroid replacement therapy only, mass was successfully regressed on follow up MRI after 4 months, and growth acceleration could be achieved.
