Visualization of fibrous dysplasia during somatostatin receptor scintigraphy.

Somatostatin receptor scintigraphy was performed on a patient with McCune-Albright syndrome and acromegaly. No evidence of pituitary disease was found, but uptake of (111)In-pentetreotide was noted in areas of fibrous dysplasia. This uptake was not changed after 6 mo of octreotide therapy. The patient's bone disease also remained stable. The possible implications of these findings are discussed.
