We report two cases of CVST with intense and diffuse dural enhancement that resulted from pachymeningitis in one patient and spontaneous intracranial hypotension in another. Pachymeningitis and spontaneous intracranial hypotension were also determined to be the underlying causes of CVST. The clinical data of these two patients are described. In patients with CVST, dural enhancement is not always a secondary change to CVST. It can be a manifestation of the underlying causes of CVST. When diffuse and intense dural enhancement is revealed, sufficient ancillary tests are warranted to rule out other potential patholooical chanoes of the dura mater those can result in CVST.展开更多

It is typically performed in patients with characteristic postural headaches due to low intracranial pressure. We report a case of a young female with an implanted Miethke Sensor Reservoir, which was used for continuous intracranial pressure (ICP) monitoring during a two-level epidural blood patch. ICP increased only with thoracic injection, suggesting thoracic EBP may have greater efficacy than lumbar EBP in treating SIH and PDPH when the site of CSF leak is unknown.展开更多
