Points To Remember
-
Occur
in almost 0.75% of skull fractures in children
-
The ongoing
normal rapid growth of the child’s brain is an aggravating factor.
-
Children may present
weeks to years later after injury with a pulsatile mass or rarely with
a depressed calcarial defect.
-
Unabating CSF
pulsations transmitted to the entrapped arachnoid protrusion result in
the remodeling of bone of the growing skull, resulting in enlargement
of the fracture line
-
The
term leptomeningeal cyst is now considered obselete.
