A high-resolution computed tomographic scan of his head did not show uncal herniation but, rather, revealed a complex fracture of the sella turcica (Panel C, arrow) and of the skull base (not shown), with impingement of the bony nerve canals and a C1 fracture.

He was discharged to his home 16 days after the injury with a hard cervical collar. Subsequently, he has done well but has had occasional vertigo and tinnitus. His ocular defects have resolved.
