摘要

目的:探讨脊椎多发性骨髓瘤（multiple myeloma

MM）的MRI表现与鉴别诊断

减少误诊。方法:回顾性分析16例经骨髓凃片或局部病灶活检病理证实的脊椎多发性骨髓瘤的MRI表现特点。结果:脊椎MM的MRI表现分为4型:正常型

1例（6.25%）

T1WI病灶呈稍高信号

T2WI呈等信号;弥漫型

9例（56.25%）

T1WI病灶呈弥漫性低信号

边界较清楚

T2WI呈稍高信号或等信号

边界欠清;局灶型

3例（18.75%）

T1WI病灶呈多发结节状、斑片状低信号

边界较清楚

T2WI呈稍高信号或等信号“;椒盐”型

3例（18.75%）

表现为弥漫性斑点状高、等、低混杂信号

边界欠清。以上各型在STIR上均呈高信号

病灶显示清楚。椎体受累常为连续性

占68.75%;椎体变形

占31.25%;附件受累

占25%;椎旁软组织肿块

占6.25%。结论:脊椎MM的MRI表现有一定特点

MRI在其诊断及鉴别诊断中有一定的价值。

Abstract

Objective:To study the MRI features and its value in diagnosis and differential diagnosis of the vertebral multiple myeloma(MM).Methods: The MRI features of 16 patients with vertebral MM proved by histology were retrospectively analyzed.Results: The vertebral MM was classified into the following four types :Normal type accounted for 6.25%

in which the lesions were mild hyper-intensity on T1WI and iso-intensity on T2WI.Diffuse type accounted for 56.25%

in which the lesions were diffuse hypo-intensity with clear border on T1WI and hyper-intensity with indistinct border or iso-intensity on T2WI.Localized type accounted for 18.75%

in which the lesions were multiple nodular or patchy hypo-intensity on T1WI and mild hyper-intensity or iso-intensity on T2WI."Salt with pepper" type accounted for 18.75%

in which the lesions were diffuse spot-like mixed hyper-

iso-and hypo-intensity.The all lesions were hyper-intensity on STIR images.The involved vertebrae were continuous

which accounted for 68.75%.The vertebral bodies were metamorphosed in 5 cases(31.25%).The appendixes were involved in 4 cases(25%).The paravertebral soft tissue mass was found in only 1 case(6.25%).Conclusion: The vertebral MM has some features on MRI.MRI is valuable in diagnosis and differential diagnosis of the vertebral MM.
