A rare case of lumbo-sacral lipoma in an adult case is reported. A 55-year-old male was admitted to the Department of Neurosurgery, Mazda Hospital, after a history of one year of urinary incontinence. Neurologically, no motor or sensory disturbance of the lower extremities was found in this patient. MRI showed a mass with high signal intensity on T2-weighted image, located between L3 to S2 vertebral segments. Metrizamide-CT scan demonstrated the outline of this hypodense mass at the same location as shown on MRI image. A L3 through L5 laminectomy was performed and the tumor was subtotally removed. Microscopic examination revealed that the tumor mass was made up of mature lipoma cells. Postoperative course of the patient was uneventful. The urinary incontinence was improved slightly. No motor or sensory deficit was found. We thought that MRI was useful for the correct diagnosis of lumbosacral lipoma. And it is best managed by operative removal of the tumor as early as possible after it is diagnosed.
报告了一例成人腰骶部脂肪瘤的罕见病例。一名55岁男性，在出现一年尿失禁病史后入住马自达医院神经外科。神经系统检查发现该患者下肢无运动或感觉障碍。MRI显示在T2加权图像上L3至S2椎体节段之间有一个高信号强度肿块。甲泛葡胺CT扫描显示该低密度肿块的轮廓与MRI图像上显示的位置相同。进行了L3至L5椎板切除术，肿瘤大部分被切除。显微镜检查显示肿瘤块由成熟的脂肪细胞组成。患者术后病程平稳。尿失禁稍有改善。未发现运动或感觉功能缺损。我们认为MRI对腰骶部脂肪瘤的正确诊断有用。并且在诊断后尽早通过手术切除肿瘤是最佳治疗方法。
