Myositis ossificans progressiva and pregnancy. A therapeutic dilemma.

Myositis ossificans progressiva is a rare but progressively debilitating autosomal dominant disease characterized by extraskeletal ossification involving muscle connective tissue. This report is the first on pregnancy and induced abortion in a patient with myositis ossificans progressiva. Intraoperative sector scanning ultrasound was of limited benefit in evacuation of the uterine cavity. Conservative management of an incomplete termination resulted in no adverse sequelae.
