Intradural spinal tumours, although relatively uncommon, can be diagnostically challenging, and often result in significant morbidity. They can be subdivided according to their cell of origin and whether they are within the cord (intramedullary) or intradural but extramedullary in location. The differential diagnosis for masses of the cauda equina region is often considered separately. Addition...

Intradural disc herniation is a serious and rare complication of intervertebral disc rupture. The preoperative diagnosis of intradural disc herniation is still difficult despite new neuroradiologic investigation possibilities including computerized tomography and magnetic resonance imaging and it is usually diagnosed by during surgery. Here we present an intradural disc herniation case at the l...

abstract our patient was a 43-year-old woman with a suboccipital headache and pain in the upper cervical region from 3 years ago with a progressive generalized weakness in the last 3 months. neuroimaging study showed a dumbell shaped lesion with compression of the spinal cord in the cervical region that was identified as a neurinoma. the tumor had been completely removed by surgery but after th...

OBJECTIVE This study used the intradural procedural time to assess the overall technical difficulty involved in surgically clipping an unruptured middle cerebral artery (MCA) aneurysm via a pterional or superciliary approach. The clinical and radiological variables affecting the intradural procedural time were investigated, and the intradural procedural time compared between a superciliary keyh...

Intradural extra-arachnoid lumbar disc herniation is a rare disease. Few MRI findings have been reported. We experienced an intradural extra-arachnoid lumbar disc herniation. We reviewed the preoperative MRI findings. Lumbar spine T2-weighted sagittal MRI showed that one line of the ventral dura was divided into two by a disc herniation. We speculated that the two lines comprised the dura and a...

Study Design Case report. Objective Presentation of an unusual case of an elderly patient with massive intradural disk herniation at the L2-L3 level. Methods Clinical and imaging data are presented after obtaining informed consent from the patient. Results A 90-year-old man suffering from sudden-onset neurogenic bladder dysfunction and lower back pain but no further neurologic deficits initiall...

Intradural disc herniation has been reported as a rare type of intervertebral disc herniation, only 32 cases reported. It remains difficult to definitively diagnose the disease before surgery. We reported a 55 year-old female patient complaints of nuchal pain and bilateral arm weakness after a trauma accident. MRI revealed a C3-C4 herniated intervertebral disc (HIVD) with a “hawk-beak sign.” CT...

Capillary hemangiomas involving the neuraxis are very uncommon. In the spinal cord, they are located mainly intradural and extramedullary.1 According to the literature, vascular lesions account for approximately 6%–7% of all intradural spinal tumors, although intramedullary capillary are extremely rare.2 To our knowledge, only four cases in conus medullaris have been previously described since ...

Acute hemorrhagic presentation of spinal schwannoma is an event rarely seen. We had ever reported a 63-yearold male presenting with acute spinal cord compression caused by a long segment of intradural extramedullary schwannoma with hemorrhage and atypical enhancement pattern. The magnetic resonance image findings included a long segmental irregular contour, intermediate signal intensity on T1-w...
