目的 研究多发性骨髓瘤的影像表现及其诊断价值。方法 分析 84例多发生性骨髓瘤的影像表现。所有病人均摄X线照片 ,2 2例CT和 10例脊椎MRI。结果 在X线片上 ,12例正常 ,4例骨质疏松 ,6 8例骨质破坏 ,2 3例伴软组织肿块。CT示 10 0 %均有骨破坏 ,8例伴软组织肿块。 10例脊椎MRI均示病变呈长T1、长T2 信号。弥漫型 3例 ,灶型 2例 ,弥漫加灶型 3例 ,“盐和胡椒”型 2例。 2例增强后示病变和增厚的硬脊膜增强。结论 多发性骨髓瘤有一定的影像表现特点和诊断价值。MRI特别是对脊椎病变优于X线平片和CT。
Objective To study the imaging features and diagnostic value of multiple myeloma. Methods The image manifestations of 84 cases of multiple myeloma were analyzed. All patients underwent radiographs, 22 cases of CT and 10 cases of spinal MRI. Results On X-ray films, 12 cases were normal, 4 cases were osteoporosis, 68 cases of bone destruction, and 23 cases had soft tissue masses. CT showed that 10% had bone destruction, and 8 cases had soft tissue lumps. In 10 cases of spinal MRI, lesions showed long T1 and long T2 signals. There were 3 cases of diffuse type, 2 cases of focal type, 3 cases of diffuse plus focal type, 2 cases of “salt and pepper” type. Two cases of enhanced posterior lesions and thickened dura mater enhancement. Conclusion Multiple myeloma has certain imaging features and diagnostic value. MRI is especially superior to X-ray plain film and CT in spinal lesions.
