摘要
目的探讨脊柱浆细胞瘤的CT特征及鉴别诊断。方法回顾性分析12例经手术病理证实的脊柱浆细胞瘤患者。均摄X线脊柱平片和CT扫描。影像学重点分析肿瘤形态学、病灶密度、发生部位、椎管和软组织的变化。结果 12例中有5例发生于颈椎,4例发生于胸椎,1例发生于腰椎,2例发生于骶椎。5例病变位于椎体,3例位于脊柱附件,4例同时累及椎体和附件。CT表现为椎体内线状骨小梁残留和终板皱褶样的骨破坏,肿瘤均匀强化。椎体不完全破坏5例,椎体完全破坏4例,椎体塌陷3例。结论脊柱浆细胞瘤单发多见,位于颈、胸椎为主,CT表现为瘤体内线状骨小梁残存和终板呈皱褶样改变。鉴别诊断包括单发血管瘤,转移瘤和巨细胞瘤。
Objective To study the CT characteristics of spinal plasmacytoma and its differential diagnosis. Methods Twelve patients of spinal solitary plasmacytomas were reviewed,who all had been confirmed by pathology. Plain films and CT scans were taken in all patients, which were used to intensively analyze the changes of morphology and lesion density, tumor location,adjacent tissue involvement and bone destruction. Results Among the 12 cases, there were 5 Cases with tumors at cervical spine ,4 at thoracic, 1 at lumbar and 2 at sacral. Tumor lesions were located at vertebra in 5 cases, at affiliated bone in 3, and both at vertebra and affiliated bone in 4. CT scans showed linear bone trabecula left in vertebra and folded bone destruction of end plate with tumor lesions equably-enhanced after contrast medium injection. Five cases demonstrated incompletely vertebral destruction,4 completely vertebral destruction and 3 completely collapse of vertebral body. Conclusion Spinal plasmacytoma is mostly solitary and is mainly located at cervical and thoracic spine. CT characteristics of the tumor are linear bone trabecula left and folded bone destruction of end plate. Differential diagnosis includes hemangiomase, metastasis and giant cell tumor.
