[Radiculo-spinal discomfort and Scheuermann's disease. 12 cases].

Twelve cases of Scheuermann's disease associated with neurological disorders are reported. The relation between the two conditions can be established through herniated disc, kyphotic angulation or spinal cyst. A more interventionist attitude is justified by the progress and results of neuroradiological investigations and surgical techniques.

[Correlations between intracranial pressure variations and EEG changes in patients with cranial trauma (author's transl)].

Polygraphic studies were performed over periods of 14 to 76 hours in 30 patients with reccent closed cranial injuries. Correlations between ICP and EEG findings were rarely found (3/16) in cases of cerebral dysfunction of mesodiencephalic or lower levels, where both ICP and EEG were usually stable. Correlations are regularly found in diencephalic or higher (10/14) levels and their presence is of favourable prognostic significance. Generally, delta waves at 1,5-2 cs, high in amplitude (type A) accompany reduced or low ICP levels,while a rapid and low voltage tracing (type B) is associated with raised or high levels of ICP. In the latter cases, a very slow (0.5 cs) and low in amplitude tracing (type C) can progressively replace the type B. The classical periodic or alternating tracing associates alternate sequences of type A and B and is observed simultaneously with type B pressure waves. These correlations are analogous with those observed during the evolution of intracranial tumors or hydrocephalus. The EEG modifications are probably related more to the pathological lesion than to a direct action of fluctuations in ICP.

[Stereotaxic technics in expanding lesions of the brain stem].

Stereotactic biopsies, according to the Talairach's system, define the histopathological data (nature, grading, spatial delimitation, evolutive potential) of brain stem lesions, precisely localized by computerized tomography scanner and magnetic resonance imaging. They are the more valued complement of the modern neuro-imaging and they prove the extreme polymorphism of theses lesions. According to this histological analysis and the volume of the lesions, it's possible to choose the best therapeutic procedure.

[Post-traumatic subarachnoid hemorrhage of the cauda equina].

A case of subarachnoid hematoma of the cauda equina is described. The lesion developed in a patient receiving anti-coagulant treatment after a seemingly ordinary fall from a ladder. Neurosurgery achieved complete regression of the neurological defects in two weeks. The mechanism of development of the lesions is discussed. This form of complication of spinal trauma is fortunately exceptional.

[Panmedullary ependymoma. A case report].

Panmedullary ependymoma is an unusual disease last reported by Fuentes in 1986. The present case is the first to have been studied by magnetic resonance, using gadolinium. The findings indicated a panmedullary lesion rather than a tumour. Histopathological investigation confirmed the hypothesis.

[Late posttraumatic syringomyelic syndromes. Pathogenetic theories apropos of 3 cases].

Three patients with a post-traumatic spinal cord cavity are described: clinical signs are identical to those of syringomyelia, but pain is more frequent. Diagnosis is made easier by magnetic resonance imaging (MRI) and a syringoperitoneal shunt is proposed for treatment. Nevertheless, if results are good, they seem worse than in idiopathic syringomyelia. The main pathogenic theories are discussed: the rupture and coalescence of microcysts developed at a distance of 1 or 2 mm from the transected spinal cord, subsequently leads to syrinx formation; haemorrhagic or ischemic post-traumatic areas could also lead to syrinx formation. Hydrodynamic factors could be expected and make the pathogenesis not far from syringomyelic one.
