Abstract Leontiasis ossea leonine facies or cervical canal stenosis are rare complications of polyostotic fibrous dysplasia PFD . This case report documents dramatic leontiasis ossea in PFD as well as post traumatic cervical cord contusion due to hyperextension injury in a patient with generalized PFD involving the cranio-facial bones axial skeleton and entire spine with secondary cervical canal stenosis. Cervical cord contusion has not been reported earlier in PFD. Background Fibrous dysplasia FD is a rare skeletal developmental disorder whereby the medulla of bone is replaced by fibrous tissue leading to distortion of bony architecture expansion and weakening of bones easy fractures joint subluxations or dislocations and compressive symptoms 1 . Four varieties of FD are recognized the monostotic form single bone involvement polyostotic form PFD multiple bones are affected craniofacial form multiple craniofacial bones are affected or a cherubic form maxilla and mandible alone are affected . PFD has a predilection for the long bones ribs spine and craniofacial bones. It is sometimes associated with the McCune Albright syndrome where café au lait spots .
