简介：我们研究了超声检测皮肌炎（DM）和多发性肌炎（PM）患者三角肌、股外侧肌（VL）和股直肌（RF）筋膜增厚的情况。方法：对7例DM和5例PM患者的筋膜厚度与54例健康对照者进行比较。结果：DM/PM组三角肌筋膜厚度是健康对照组的2倍（1.15 mm vs.0.54 mm; P < 0.001）。8例患者三角肌筋膜明显增厚（>5 SD）。只有1例临床表现轻微的患者三角肌筋膜厚度正常。4例患者还出现VL和/或RF筋膜增厚。结论：DM和PM患者的三角肌筋膜厚度显著增加，而四头肌仅在严重受累的患者中显示筋膜增厚。这项研究表明，伴随筋膜炎可能比以前认为的更常见。
Introduction: We investigated the use of ultrasound to detect fascial thickening of the deltoid, vastus lateralis (VL), and rectus femoris (RF) muscles in dermatomyositis (DM) and polymyositis (PM). Methods: Fascial thickness of 7 DM and 5 PM patients was compared with that of healthy controls (n = 54). Results: The deltoid fascial thickness was 2-fold greater in the DM/PM group (1.15 mm vs. 0.54 mm; P < 0.001) compared with healthy controls. Eight patients had markedly thickened deltoid fascia (>5 SD). Only 1 patient with a mild clinical presentation had normal deltoid fascial thickness. Four patients also had fascial thickening of the VL and/or RF. Conclusions: Deltoid fascial thickness was increased significantly in DM and PM patients, whereas the quadriceps muscle only showed thickened fascia in severely affected patients. This study suggests that a concomitant fasciitis may be present more often than previously believed.
