[Spinal cord compression by arachnoid cysts].

Spinal arachnoid cysts are considered to be rare entities, intradural locations are even less common. We report two cases of patients (two women aged 77- and 21-year-old) who presented spinal cord compression by intradural arachnoid cysts. For the second patient, repeated surgical procedures were necessary to improve the neurological status. After presenting the case reports, we expose the pathophysiological mechanisms and clinical features, and the surgical difficulties of treating this rare cause of spinal cord compression.

[Paraplegia and the sitting position].

The sitting position in neurosurgery may lead to complications such as air embolism and neurological complications. We report the case of a 16-year-old male who suffered from post-operation paraplegia after surgery for Arnold Chiari disease. This patient had several risk factors and serious morphological spinal abnormalities. We propose to include monitoring of somatosensory evoked potentials (SSEP) during this surgery in order to detect this type of devastating incident.

[Primary dural lymphoma. A case report].

Primary central nervous system lymphoma is an invasive disease in both HIV-positive and HIV-negative patients. Atypical presentations, including leptomeningeal involvement often described in cases with aggressive histology, have been reported but primary meningeal B-cell lymphoma appears to be very rare. A 40-year-old immunocompetent man developed a voluminous frontoparietal cranial vault tumor. The neurology examination demonstrated a large extra-axial mass involving the anterior part of the superior longitudinal sinus. The tumor extended through the cranial vault, without osteolysis, and grew in the subcutaneous tissue. Craniotomy was performed and the entire mass was resected without neurological deterioration. Pathology reported B-cell lymphoma. No other localization was found. Primary B-cell meningeal lymphoma, as illustrated in this case, can be another atypical presentation of CNS lymphoma.

[Neuronavigation in third ventricle tumors].

The authors present the results of neuronavigation as a help to open neurosurgery for the tumors of the third ventricle. From January, 1995 to August, 1999, six image-guided surgical procedures were performed to remove third ventricle lesions : 4 colloïd cysts, 1 ependymoma, and 1 craniopharyngioma. The operative approach was transcortical in 5 cases, and transcallosal in 1 case. The use of neuronavigation allows a decrease of the surgical trauma during the surgical approach. The procedure secures the neurosurgeon in the choice and execution of his pathway to the target. It becomes however less accurate after opening the ventricle, because of the brainshift induced by the loss of cerebrospinal fluid becomes important. Nevertheless, neuronavigation is useful in the surgery of the third ventricle, especially if it is used with neuroendoscopy.

Microsurgical DREZotomy for pain due to brachial plexus avulsion: long-term results in a series of 37 patients.

The authors analyzed the postoperative and long-term results of the microsurgical DREZotomy procedure performed in 37 patients suffering from chronic pain due to brachial plexus avulsion. The evaluation was based on clinical parameters. The immediate results consisted of good pain relief (pain relief > 75%) in 79% of the patients. A long-lasting good pain relief has been achieved in 66.5% of the patients with a mean follow-up of 60 months (range 12-120). The morbidity rate was 5%.
