BACKGROUND AND PURPOSE CT myelography has historically been the test of choice for localization of CSF fistula in patients with spontaneous intracranial hypotension. This study evaluates the additional benefits of intrathecal gadolinium MR myelography in the detection of CSF leak. MATERIALS AND METHODS We performed a retrospective review of patients with spontaneous intracranial hypotension w...

understood entity resulting from CSF leakage or from venous hypotension causing increased CSF absorption. It causes a range of symptoms from orthostatic headaches to coma. MRI and CT myelography are the investigations of choice in demonstrating CSF leaks as presumed sites of dural defects. CT myelography has traditionally been the first diagnostic tool, but this necessitates lumbar puncture for...

We used magnetic resonance (MR) myelography in ten patients with injuries to the brachial plexus and compared the findings with those obtained by conventional myelography and postmyelographic CT (CTM). In the presence of complete nerve-root avulsion (seven cases), a post-traumatic meningocele was detected by MR myelography. In injuries to the upper roots (three cases) MR myelography showed abno...

RATIONALE Acute neurological deficits following spinal surgery commonly result from epidural hematoma, surgical trauma, vascular compromise, and graft or hardware impingement, with the cause identified by magnetic resonance imaging (MRI). We present a rare case of dynamic paraspinal muscle impingement after C1 posterior arch laminectomy, which was diagnosed by myelography, with no significant f...

Computed tomography (CT) myelography is used occasionally in the diagnosis of cervical spondylomyelopathy, but the type of lesion found in large- versus giant-breed dogs using this modality has not been characterized. Our purpose was to report the frequency of compressive lesions in large- and giant-breed dogs with cervical spondylomyelopathy and imaged using CT myelography. Fifty-eight dogs we...

We describe an 18-year-old male with cervical flexion myelopathy with Hirayama disease-like features who showed apparent long tract signs. He first experienced insidious-onset hand muscle weakness and atrophy at the age of 15. Subsequently, he developed sensory disturbance in his lower limb. Neurological examination revealed atrophy and weakness in the right hand and forearm, pyramidal signs in...

BACKGROUND Headache after cervical or lumbar puncture has long been attributed to early mobilization; however, there is little evidence for this. We performed a systematic literature review and meta-analysis of randomized controlled trials to assess whether longer bed rest is better than immediate mobilization or short bed rest in preventing headache. METHODS We searched EMBASE (1988 to March...

A combined clinical myelographic and computed myelographic study was performed in 30 patients with cervical spondylotic myelopathy; computed myelography was also performed in 16 control patients. Good correlation was found between degree of deformity of cross-sectional shapes of the cord and the outcome of surgery, and measurements of anteroposterior diameter and area of the cord seemed helpful...
