目的提高对多发骨髓瘤的影像诊断水平。方法分析MRI室近10年来经临床和病理证实的16例多发骨髓瘤的影像学资料。结果 16例均行X线检查,主要表现为穿凿样溶骨性破坏、骨质疏松、病理性骨折,4例未见异常。CT表现为穿凿样溶骨性病变或骨质破坏。MRI表现8例弥漫型,3例局灶型,1例椒盐型,4例弥漫加局灶型。结论多发性骨髓瘤有一定影像特点,对脊椎病变MRI比X线和CT有一定优势,尤其对早期MM诊断有较高价值。
Objective To improve the imaging diagnosis of multiple myeloma. Methods The MRI data of 16 cases of multiple myeloma proved clinically and pathologically in the past 10 years were analyzed. Results 16 cases underwent X-ray examination, mainly manifested as wear through osteotomy osteolytic destruction, pathological fractures, 4 cases no abnormalities. CT showed wear through osteotomy osteolytic lesions or bone destruction. MRI showed diffuse 8 cases, 3 cases of focal type, 1 case of salt and pepper, 4 cases of diffuse plus focal type. Conclusion Multiple myeloma has some imaging features, and has certain advantages for X-ray and CT of spine lesions, especially for the diagnosis of early MM.
