The magnetic resonance imaging (MRI) features of two cases of malignant lymphoproliferative disease involving skeletal muscle are presented. In both cases involved muscles were quantitatively and subjectively hypointense to fat on T1-weighted spin echo images, hypointense or isointense on T2-weighted spin echo images, and hyperintense on short tau inversion recovery (STIR) images. The findings suggest that lymphoproliferative disease should be considered as an etiology of a skeletal muscle lesion that is hypointense or isointense to fat on T2-weighted spin echo magnetic resonance images.
本文报告了两例累及骨骼肌的恶性淋巴增殖性疾病的磁共振成像（MRI）特征。在这两例病例中，受累肌肉在T1加权自旋回波图像上相对于脂肪在定量和主观上均呈低信号，在T2加权自旋回波图像上呈低信号或等信号，在短tau反转恢复（STIR）图像上呈高信号。这些发现提示，对于在T2加权自旋回波磁共振图像上相对于脂肪呈低信号或等信号的骨骼肌病变，应考虑淋巴增殖性疾病为其病因之一。
