title: Myositis ossificans circumscripta with spontaneous healing of a cortical cyst.
abstract: We report a case of myositis ossificans circumscripta with an initial periosteal reaction and subsequent development of a cyst in the underlying cortex. All the roentgenographic abnormalities resolved spontaneously and permanently. The unusual course may have been due to formation of a subperiosteal hematoma at the time of development of the soft tissue ossification.
