[Progressive myositis ossificans. Utility of bone scintigraphy]

47 year old woman affected by myositis ossificans, with muscular calcifications in her evolution. Bone scintigraphy showed increased polyfocal activity as well as uptake of different intensity in soft tissues. The bone scintigraphy allows for early identification of ossification areas in soft tissues, as it can even detect injuries earlier than that observed with other image techniques. It is considered to be very useful in the diagnosis and establishment of the extension of the process, as well as follow-up.
