Left occipital scalp haematoma. Non-displaced left occipital bone skull fracture crosses the transverse sinus and is associated with a venous extradural haematoma. It is unclear if sinus thrombosis is present and a CTV should be obtained.
Fracture extends anteriorly to involve the left condylar canal, hypoglossal canal and jugular foramen. A fracture line is seen to extend through the anterior wall of the left foramen spinosum with no definite fracture of the left carotid canal identified, however, the fracture is seen continuing into the pituitary fossa, sphenoid sinus, right ethmoid air cells and right orbit (without displacement or haematoma). A few tiny bubbles of air mark the trajectory of the fracture.
Small right temporal contusions (contrecoup) with associated right convexity subdural haemorrhage measuring up to 6 mm. Right parafalcine subdural haematoma measures up to 4 mm. Right traumatic parietal subarachnoid blood. No intraventricular blood. No hydrocephalus.
