“The breeze at dawn has secrets to tell you. Don’t go back to sleep.”
– Rumi (1207-1273), Persian poet, jurist, theologian and mystic.
The dense dura sign
I call thus a densification at the base of the skull along bone margins seen on a gross cranial CT study.
After an accident, the usual radiological routine consists of cervical X-Rays and a “debulking” cranial CT.
Caution is taken at the beginning, stabilizing the cervical spine in a collar, a measure which might be dropped later on.
Such politics harbors the potential risk of missing a lesion of the cranio-vertebral junction.
If non-displaced, the initial study might overlook it.
Those are a few types, summed as so-called decapitation injuries.
They are all highly unstable, and a transection of the vertebral cord is the result, if handled without care.
