Abstract
McCune-Albright syndrome is a rare and challenging disorder characterized by a triad of cutaneous, bone and multiple endocrine abnormalities. We present the case of a 15-year-old female with varied symptoms including precocious puberty, prolactinoma, polyostotic fibrous dysplasia, and hyperthyroidism. On examination, she had a palpable nodule in the right lobe of the thyroid with an atrophic left lobe on ultrasonography. Thyroid scan in this patient posed a diagnostic challenge which was resolved with additional single-photon emission computed tomography/computed tomography (SPECT/CT). On SPECT/CT, she was diagnosed with autonomously functioning thyroid nodule and treated with 15 mCi of (131)I.
