Focusing only in the intracranial compartment, what is the relevant finding related to the extensive facial/orbital trauma?
Right anterior temporal extradural haemorrhage.
What is the origin of this bleeding?
The anterior temporal extradural haematomas are considered to have a venous source of bleeding (spheno-parietal sinus or its major draining veins) instead of the expected arterial origin of the extradural haemorrhages.
Right anterior temporal extradural haematoma measuring 12 mm in depth. This exerts minimal mass effect on the temporal pole. No new intracranial haemorrhage. No hydrocephalus.
Right maxillary, orbital, and frontal bone fractures are present (not shown). Right-sided proptosis.
