Abstract:
:The magnetic resonance (MR) demonstration of a pituitary adenoma associated with McCune-Albright syndrome is presented. A useful role for routine MR imaging of the sella turcica in all cases of clinically suspected McCune-Albright syndrome is suggested. This is especially important in patients with leontiasis ossea secondary to polyostotic fibrous dysplasia involving the craniofacial bones and skull base.
