既然能肯定诊断，再去排除模拟或相关病症似乎说不通，如高度怀疑，要做鉴别诊断可以这

In the presence of sufficient clinical findings to ascertain the PMR case definition, a safe and specific approach should be adopted to exclude relevant mimicking or associated conditions, e.g. non-inflammatory, inflammatory (such as giant cell arteritis or rheumatoid arthritis), drug-induced, endocrine, infective and neoplastic conditions.

在有足够的临床发现以确定PMR病例定义的情况下，应采用安全和具体的方法排除模拟或相关病症，，如非炎症性、炎症性（如巨细胞动脉炎或类风湿性关节炎）、药物诱导、内分泌、感染性和肿瘤性疾病。

问题：既然能肯定诊断，再去排除模拟或相关病症似乎说不通，如高度怀疑，要做鉴别诊断可以这么说。
