Actual bleeding in the subdural or epidural region is even less common with most cases occurring in the epidural space in children in conjunction with blunt trauma and skull base fracture or tectorial membrane injury.
Such a fracture is classified as type I, is considered an impaction fracture of the occipital condyle and is potentially unstable, as the ipsilateral alar ligament may be incompetent; however, if the tectorial membrane and contralateral alar ligament are preserved, sufficient ligamentous support may remain to preserve stability.
A diagnosis of tectorial membrane injury associated with REH, venous perimedullary subrachnoid haemorrhage and compressive oedema of the ventral medulla was made.
2) Posteriorly, the tectorial membrane originates on C2 and extends to the clivus.
