[Predictive value of postural and dynamic walking parameters after high-volume lumbar puncture in normal pressure hydrocephalus].

Introduction: Normal pressure hydrocephalus (NPH) was described by Adams et al. (1965). The common clinical presentation is the triad: gait disturbance, cognitive decline and urinary incontinence.

[Intracranial primary epidermoid carcinoma].

We report a case of intracranial primitive epidermoid carcinoma localized in the right temporal fossa in a 40-year-old man. The patient was submitted to surgical removal of his tumor and radiotherapy. Unfortunately, the survival time was six weeks after the operation.

Intraspinal cervical degenerative cyst. Report of three cases.

The authors report three cases of cervical degenerative cysts causing medullary or radiculomedullary compression. Anatomicopathological examination confirmed the fibrous nature of the cyst wall and the absence of a synovial layer. One of the cysts was embedded in the ligamentum flavum, whereas the other two were most lateral and adherent to the facet joint.

[Mature lumbar multi-tissue dysembryoma of the spinal cord with sacral spina bifida occulta].

The authors report the case of a 28-year-old woman who presented with L5 bilateral sciatica associated with perineal sensory disorders. During surgery, a mature pluritissular dysembryoma originating in a tethered spinal cord was discovered at the level of the L2-L3 intervertebral space. Following removal of the lesion, all symptoms disappeared.

Treatment of severe traumatic lesions of the dorsolumbar spine using Roy-Camille's apparatus. A clinical study of 121 cases together with technical considerations.

The authors report 121 cases of surgically treated severe lesions of the dorsolumbar spine. One single technique has been used: posterior osteosynthesis using Roy-Camille's plates.
