abstract the current mainstay of treatment in spontaneous intracranial hypotension (sih) is an epidural blood patch (ebp). although magnetic resonance imaging (mri) has a well-established role in the diagnosis of sih, imaging features regarding the treatment efficacy of ebp have rarely been discussed. we therefore sought to investigate and compare the sequential brain mri studies before and aft...

Spontaneous intracranial hypotension (SIH) is an increasingly recognised syndrome. Postural headache with typical findings on magnetic resonance imaging (MRI) are the key to diagnosis. Orthostatic headache, low cerebrospinal fluid opening pressure, and diffuse meningeal enhancement on post-contrast T1-weighted MRI brain studies are the major features of this increasingly recognised syndrome. He...

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...

Spontaneous intracranial hypotension is a rare benign and usually self-limited condition of unknown aetiology. Four cases are presented that illustrate how the MRI features may support a diagnosis suggested on clinical grounds. The MRI findings include diffuse symmetric smooth dural thickening and enhancement, not only at the cranial level, but also involving the cervical spinal dura, subdural ...

An 18-year-old man with Marfan syndrome and migraine headaches presented with acute worsening of headaches with postural changes following spinal fusion surgery for scoliosis. Lumbar spine MRI done before surgery showed diffuse dural ectasia (figure 1). Brain MRI after surgery showed distended transverse and sagittal dural venous sinuses and an enlarged pituitary gland suggesting intracranial h...
