Info
There is bilateral cerebral hemisphere convexity subdural fluid with mild mass-effect, mild compression of lateral ventricles and effacement of cerebral sulci.
Case Discussion
Intracranial hypotension leads to alterations in the equilibrium between the volumes of intracranial blood, CSF, and brain tissue (Monro-Kellie hypothesis). A decrease in CSF volume leads to compensatory dilatation of the vascular spaces.
A non-targeted epidural blood patch is often used in cases of spontaneous intracranial hypotension, on the assumption that the leak is from the spine, with variable success.
