Myositis Ossificaris Circumscripta [MOC] is a rare benign disorder characterized by heterotopic ossification of soft tissues. The limbs are electively affected Spontaneons regression can occur without treatment in most patients. We report two cases of MOC. The first in a 22 yen-old male, was localised in the knee, after a period of intensive physical training with functional disorder and surgical treatment. In the second, occurring spontaneously in a 38-year-old female and interesting the triceps brachii, imaging findings were specific and we did not need histopathologic confirmation. The outcome was favourable in both patients. We report the clinical features imaging findings and therapeutic control of this pathology
