OCCIPITAL BONE FRACTURE
Cranial cerebral fractures may be linear or may involve diastasis (separation) of sutures. Skull fractures should be further characterized by depression if present. Important clinical signs of skull base fracture include CSF rhinorrhea or otorrhea, battle's sign, raccoon eyes, hemotympanum or cranial nerve palsy (7th or 8th).
The arrow in this image points to an occipital bone fracture. Additional air fluid levels are noted within the maxillary sinus on the left as well as air within the left infra-temporal fossa and subcutaneous air involving the left eyelid.
