A Patient with Acromegaly Presenting with Polyostotic Fibrous Dysplasia on Bone Scan: McCune-Albright Syndrome

We report a 43-year-old male with acromegaly who underwent pituitary adenomectomy in 1989. Recently, the patient presented with pain in the right hip. X-ray examination showed multiple cystic lesions in the right pelvis and femur. We present the consecutively performed Tc-99m HDP bone scan that shows features of polyostotic fibrous dysplasia. The coincidence of acromegaly with fibrous dysplasia established the diagnosis of an uncommon manifestation of the McCune-Albright Syndrome. This is typically characterized by fibrous dysplasia, cafe-au-lait macules and hyperfunctioning endocrinopathies.
