OBJECTIVE To describe a novel spinous process-splitting hemilaminoplasty technique for the surgical treatment of intradural and posterior epidural lesions that promotes physiological restoration. METHODS The spinous process was split, the area of the facet lamina junction was drilled, and en bloc hemilaminectomy was then performed. After removing intradural and posterior epidural lesions, we ...

BACKGROUND Ependymoma is a glial tumor that occurs in the central nervous system. The intradural extramedullary location of this neoplasm is very rare. The authors report a case of spinal intradural extramedullary ependymoma in a male and discuss its pathogenesis as well as its clinical, radiological, and therapeutical features. CASE DESCRIPTION A 31-year-old man was admitted at the author's ...

Neurological deterioration sometimes follows removal of cerebro-spinal fluid by lumbar puncture below a spinal block caused by a tumour. Experience has shown that similar impaction of a spinal intradural tumour may occur following the draining of hydrocephalus. We have used the term "upward spinal coning " to describe this and report four cases in which impaction of an intradural metastasis occ...

Spinal cord glioblastoma (SG) accounts for 1.5% of all spinal tumors and has a poor prognosis with survival ranging from 2 to 26 months from presentation. A 57-year-old male presented with one week of paraparesis and contrasted magnetic resonance imaging (MRI) findings of an epidural enhancing thoracic mass suspicious for an epidural abscess. Intraoperative and pathologic findings revealed SG. ...

A 24-year-old man with tuberculosis meningitis developed acute paraplegia and sensory disturbances 5 weeks after receiving conventional antituberculous therapy. Magnetic resonance imaging revealed an intradural extramedullary long segmental mass mimicking en plaque meningioma at the T2-T6 vertebrae levels. Prompt surgical decompression was performed. A histology examination of the mass revealed...

A 51-year-old woman presented with a rare completely intradural and extramedullary spinal ganglioneuroma associated with multiple hamartoma syndrome and manifesting as complaints of neck pain and dizziness persisting for 8 months. Magnetic resonance imaging of the spinal cord revealed an intradural extramedullary lesion at the C1 level. She underwent right suboccipital craniectomy and C1-2 hemi...

A 36-year-old female patient presented with shoulder pain experienced over a period of one year and progressive weakness in both legs for one month. A magnetic resonance imaging scan revealed an intradural extramedullary (IDEM) fusiform mass about 9.8 cm in length, heterogeneously enhanced at the level of C6-T4 with spinal cord compression. At the time of surgery, the surgeon found an encapsula...

The parasitic tapeworm Echinococcus granulosis causes hydatid disease, which is rarely encountered in nonendemic regions. It is a progressive disease with serious morbidity risks. Rarely, these cysts are found in the spine. They are mainly found epidurally, originating from direct extension from pulmonary, abdominal or pelvic infestation. Nevertheless, the main mechanism for intradural involvem...
