我们研究了臂丛磁共振（MR）成像是否有助于区分多灶性运动神经病变（MMN）和下运动神经元疾病（LMND），以及异常是否类似于慢性炎症性脱髓鞘性多根神经病变（CIDP）。我们将9名MMN患者的臂丛磁共振图像与5名CIDP患者、8名LMND患者和174名对照者的扫描结果进行了比较。在2名MMN患者和3名CIDP患者中，MR图像显示臂丛t -2加权图像上的信号强度增加。另外两名MMN患者在t -2加权图像上表现出更集中，信号强度增加，一名患者仅发生在腋窝，另一名患者发生在腋窝和根的腹侧支。8例LMND患者的臂丛MR图像正常。mri异常的分布与患者症状的分布相一致，MMN为不对称，CIDP为对称。这些发现表明；MMN患者的臂丛mri异常与CIDP相似，可能有助于区分MMN和LMND。
We studied whether magnetic resonance (MR) imaging of the brachial plexus is useful to distinguish multifocal motor neuropathy (MMN) from lower motor neuron disease (LMND) and whether abnormalities resemble those of chronic inflammatory demyelinating polyradiculoneuropathy (CIDP). We compared MR images of the brachial plexus of nine patients with MMN with scans from five patients with CIDP, eight patients with LMND, and 174 controls, In two patients with MMN, and in three patients with CIDP, the MR images showed an increased signal intensity on the T-2-weighted images of the brachial plexus. Two other patients with MMN demonstrated a more focal, increased signal intensity on the T-2-weighted images, occurring in one patient only in the axilla, and in the other patient in the axilla and in the ventral rami of the roots. MR images of the brachial plexus of eight patients with LMND were normal. The distribution of the MR imaging abnormalities corresponded with the distribution of symptoms of the patients: asymmetrical in MMN and symmetrical in CIDP. These findings demonstrate that; MR imaging abnormalities of the brachial plexus in patients with MMN resemble those seen in CIDP and may be useful to distinguish MMN from LMND.
