PURPOSE A recently identified and treatable cause of spontaneous intracranial hypotension (SIH) is cerebrospinal fluid (CSF)-venous fistula, and a recently described computed tomography myelogram (CTM) finding highly compatible with but not diagnostic of this entity is the hyperdense paraspinal vein sign. We aimed to retrospectively measure the prevalence of the hyperdense paraspinal vein sign ...

We describe the case of a 40-year-old man with spontaneous intracranial hypotension who presented with cervical radiculopathy associated with epidural venous engorgement. Epidural venous engorgement can occur secondary to intracranial hypotension and manifests intracranially as pachymeningeal venous engorgement. In the cervical spine, two cases of epidural venous engorgement due to intracranial...

BACKGROUND Spontaneous intracranial hypotension (SIH) results from leaks developing in the dura mater. The major symptom is orthostatic headache which gradually disappears after lying down. Lumbar epidural blood patches (EBPs) can be effective in relieving headaches, however, thoracic and cervical EBPs have also been applied to alleviate the symptoms. OBJECTIVE AND METHODS Retrospective colle...

Spontaneous intracranial hypotension is a clinical entity characterized by orthostatic headache, low CSF pressure and specific cranial imaging techniques. Headache can be accompanied by the symptoms such as tinnitus, vertigo, diplopia, nausea and vomiting. It is important for the diagnosis to show the level of CSF leakage. Epidural blood patch should be planned for the treatment of patients wit...

BACKGROUND AND PURPOSE Optimal diagnosis and management of spontaneous intracranial hypotension remains uncertain. CT-guided blood patching has been described but has not been evaluated in larger case series. We sought to evaluate the efficacy of CT-guided blood patching of observed or potential CSF leaks in spontaneous intracranial hypotension. MATERIALS AND METHODS Patients referred for eva...

Symptomatic overdrainage of cerebrospinal fluid (CSF) can be seen in shunted hydrocephalus patients and in non-shunted patients with spontaneous intracranial hypotension (SIH). In these patients, intracranial pressure (ICP) monitoring often reveals negative static ICP, while it is less understood how the pulsatile ICP (cardiac induced ICP waves) is affected. This latter aspect is addressed in t...
