Dermatomyositis is an inflammatory myopathy with the characteristic features of skin rash and myopathy. We here present a known case of dermatomyositis evaluated with F-FDG PET/CT for the presence of any occult malignancy. The scan was negative for the presence of any malignancy. However, it revealed multiple intensely FDG avid colonic strictures that were later proven on colonoscopic biopsy to be ulcerative colitis. Also, a well-known association of bilateral sacroilitis was simultaneously demonstrated on the scan. The present case demonstrates that F-FDG PET/CT imaging can serve as a one-stop shop imaging modality in dermatomyositis by facilitating detection of occult primary if any and by providing insight into other rare systemic associations.
皮肌炎是一种具有皮疹和肌病特征的炎性肌病。我们在此呈现一例已知的皮肌炎病例，该病例接受了F-FDG PET/CT检查以确定是否存在隐匿性恶性肿瘤。扫描结果显示未发现任何恶性肿瘤。然而，它发现了多个FDG摄取强烈的结肠狭窄，后来经结肠镜活检证实为溃疡性结肠炎。此外，扫描同时显示了双侧骶髂关节炎这一众所周知的关联。本病例表明，F-FDG PET/CT成像可通过促进隐匿性原发灶（如有）的检测并深入了解其他罕见的全身关联，成为皮肌炎的一站式成像模式。
