This radiograph shows a patient with cleidocranial dysplasia. The right clavicle is entirely absent and the left clavicle is severely hypoplastic. The shoulders are depressed bilaterally due to lack of articulation with the axial skeleton. Metallic foreign objects projecting of the left acromion process are most likely retained nerve stimulator leads. Unfused spinous processes are seen in the lower cervical and upper thoracic spine.
The remainder of the exam is unremarkable.
This radiograph shows a hypoglossal nerve stimulatimplanted in the chest wall,ert with the patient’s breathing to prevent sleep apnea.
Incidentally, this patient also had a prior anterior cervical discectomy and fusion (ACDF), with the plate and screws projecting over the lower cervical spine.
This radiograph shows a vagal nerve stimulator. The generator projects over the left hemithorax and a single thin lead tracks to the left base of neck. At first glance this may be mistaken for a pacemaker, but the course and caliber of the lead indicate that this is a different device. The exam is otherwise unremarkable.
