STUDY DESIGN: Case report. OBJECTIVE: To describe the clinical presentations, radiological features and clinical progress of a rare case of @entity84 of the lumbar spine. SETTING: Regional Hospital, Hong Kong, China. METHOD: A 54-year-old male @entity1 presented with @entity1643 and left sciatica. X-ray and MRI revealed @entity5 infiltration of the fifth lumbar vertebrae and left paraspinal muscles, which was found to be a @entity84 by repeated open biopsies. The @entity5 was removed surgically by combined anterior and posterior approaches, followed by spinal fusion and instrumentation. RESULTS: The anterior tricortical bone graft was complicated with @entity174 and nonunion. Surgical re-exploration confirmed local recurrence of @entity5 macroscopically and histologically. The @entity1 developed symptoms and signs of @entity1971 gradually despite repeated surgery and irradiation. The @entity1 eventually died of complications of local recurrence and @entity51 at 3 years and 8 months after the first operation. CONCLUSION: This is the first case report of @entity84 of the lumbar spine. The clinical profile of this @entity1 and the evidence from the literature review suggests that @entity84 has a @entity146 with high recurrence and mortality rate.
