An odd and serious "disc bulging"!

BACKGROUND AND IMPORTANCE: Cauda equina syndrome is a common acute medical condition, usually caused by large degenerative disc herniation or metastatic lumbar disease. We describe a patient who presented with a lesion featuring both discal and tumoral characteristics. CLINICAL PRESENTATION: A 41-year-old woman presented with ongoing back pain, progressive lower-limb weakness and sphincter disorder. Magnetic resonance imaging showed a very odd-looking large anterior epidural lesion originating from the L3-L4 space and severely compressing the roots of the cauda equina. Partial surgical decompression was performed in emergency. At a later time, redo surgery was performed to maximize resection, and was unfortunately followed by several complications. After 6 surgical procedures including a ventriculo-peritoneal shunt insertion and intensive rehabilitation, the patient could walk independently with the aid of one crutch. Following collegial review, the diagnosis of low-grade chondrosarcoma of the intervertebral disc was suggested. CONCLUSION: We report on a very unusual and therapeutically challenging spinal tumor diagnosed as low-grade chondrosarcoma of discal origin, an entity never previously described.

[Role of surgery in the management of vertebral metastases. General revue]. / Place de la chirurgie dans la prise en charge des métastases vertébrales. Revue générale.

The spine is the most common site of skeletal metastases. Treatment decisions for patients with spinal metastases can be challenging and greatly depend on survival prognosis. Surgery remains a valuable weapon in the therapeutic arsenal. A review of the literature describing the role of surgery, the various surgical approaches and the prognostic scores available for the management of spinal metastases was performed and summarized. Surgery for spinal metastases has 3 main objectives: management of pain, achievement of mechanical stability and preservation or restoration of neurological function. A variety of surgical approaches are available and depend on location of tumor, presence of instability, neurological status, oncologic prognosis, general performance status and subsequent treatment measures. The goal of any therapeutic course for a spinal metastasis is the best oncologic and functional result with the least aggressive treatment. Novelty surgical and adjunctive measures allow a multidisciplinary approach to the metastatic spine.

[Brainstem cavernomas: surgical experience at the CH Sainte-Anne general hospital]. / Cavernomes du tronc cérébral: l'expérience chirurgicale du centre hospitalier Sainte-Anne.

BACKGROUND AND PURPOSE: No standard treatment for brainstem cavernoma has been established because of the lack of sufficient data about the natural history of these lesions in a highly functional location with potential difficult surgical accessibility. METHODS: We present a series of 82 brainstem cavernomas managed at the Sainte-Anne Hospital. Surgery was undertaken for 25 with stereotactic biopsy for 9 and direct surgery for 19 (3 after biopsy). RESULTS: Surgical outcome was good or fair for 17 patients. Two patients worsened and one died. Biopsy results were disappointing with high morbidity (4 patients with 2 permanent deficits). Histological diagnostic was possible for all biopsies. CONCLUSION: In light of these results, an active surgical attitude could be proposed for cavernomas in an accessible locations which have produced at least one previous hemorrhage. Stereotactic biopsies for suspect brainstem cavernoma must be avoided.

[Anterior cervical discectomy with or without bone graft placement in the treatment of cervical radiculopathy. Long-term results]. / Discectomie cervicale antérieure avec ou sans greffe dans les conflits radiculaires. Résultats à long terme.

BACKGROUND AND PURPOSE: Anterior approach for cervical radiculopathy is a frequently performed operation in neurosurgery. The goal of this study is to evaluate the short and long-term results of anterior cervical discectomy with and without fusion. METHODS: Between 1984 and 1999, we operated on 101 patients presenting with cervical radiculopathy by an anterior approach. The operation consisted of one-level discectomy in 74 cases, two-level discectomy in 25 cases and three-level discectomy in 2 cases. Eighty-four out of 130 levels operated on were fused. Evaluation was done following a consultation with dynamic cervical X-rays and by telephone using a detailed questionnaire. Follow-up was obtained in 91 cases with a mean of 54 months in fused patients, and a mean of 45 months in the non-fused patients. RESULTS: Post-operative results were good in 95% in the 2 groups of patients. We encountered 8 complications, all in patients operated with bone graft placement. Five patients were reoperated on at an adjacent level, 4 being fused previously. CONCLUSIONS: The 2 techniques are comparable in term of goods results at short and long-term follow-up. Anterior discectomy without fusion is associated with less complications, less post-operative pain, and less operative time cost.
