Intradural disc herniation is found in only 0.3% of cases of disc herniation. The majority of these (>95%) are found in the lumbar region, with fewer than 5% occurring in the thoracic region [1,2]. While imaging occasionally raises suspicion of an intradural component to a herniated disc, the majority of cases are diagnosed intraoperatively [1-6]. We describe a case of an intradural thoracic di...

The authors present a unique case of an intradural extramedullary ganglioneuroma in the thoracic spine of an adult. Intraspinal ganglioneuromas are rare, benign tumors of sympathetic nervous tissue origin, but exclusively intradural ganglioneuromas have not been reported.

BACKGROUND Calcifying nonneoplastic pseudoneoplasms of the neuraxis (CAPNON) have been reported in 59 cases in literature, however, they rarely involve the spinal cord. Owing to the advances in immunohistochemical markers, their structure and origin are better understood now. CASE REPORT We present the case of a 72-year-old female who had longstanding history of low back pain that exacerbated...

We reviewed the medical records of 233 patients having electrodiagnostic evidence of polyradiculopathy. Patients with polyneuropathy or incomplete diagnostic evaluation were excluded. A clinical diagnosis was secured in 92 of the 118 remaining patients. Patients were separated into three groups based upon the anatomic location of root involvement: extradural (55), intradural-extraaxial (23), an...

BACKGROUND AND PURPOSE The frequency and amount of intracranial, intradural inflammatory vessel wall enhancement in giant cell arteritis remain unclear. The purpose of this work was to prospectively assess the intracranial extent of vasculitic changes in patients with giant cell arteritis using a dedicated MR imaging protocol optimized for assessment of mural changes of intracranial arteries. ...

OBJECTIVE The purpose of this study was to evaluate the usefulness of proton density magnetic resonance (PD MR) imaging for localization of paraclinoid internal carotid artery aneurysms. MATERIALS AND METHODS From April 2014 to April 2015, 76 unruptured paraclinoid aneurysms in 66 patients were evaluated using PD MR and angiography (CT/MR angiography or digital subtraction angiography). The l...

Intradural tumours of the spine are usually benign and have a good prognosis, if they are diagnosed and removed early. Lumbar disc herniation is a common cause of chronic, acute, or recurrent lumbar radiculopathy. However, to date, there have been no reports of progressive neurological deficiencies due to the co-existence of two significant pathologies contributing to intradural and extradural ...

Although metastatic spread of prostate carcinoma to the spinal column is common, involvement of the spinal intradural extramedullary compartment is exceedingly rare. Presentation of intradural metastases tends to be late in the course of the disease, is frequently associated with cerebral metastasis and the role of surgery is limited to palliation and prevention of neurological deterioration. H...
