A case of craniocleidal dysostosis presenting with vascular complications.

A case of craniocleidal dysostosis was presented. In spite of the skeletal abnormalities present, the disease was not diagnosed until the patient, a married woman of 63, developed ischaemia of her right upper limb, followed by cerebral symptoms. An arch aortogram demonstrated an occlusion of the first part of the right subclavian artery involving the origin of the vertebral artery and a post-stenotic dilatation of the left subclavian artery due to costoclavicular compression. Such vascular abnormalities have not been previously described in this condition.
