Abstract：
We report the case of an 11-year-old girl with a recent diagnosis of common B-cell acute lymphoblastic leukemia who presented with Pseudomonas aeruginosa pyomyositis of the left lower limb during severe neutropenia associated with the induction phase of chemotherapy.
Presenting signs included fever, leg pain, and refusal to walk. Popliteal knee ultrasonography was unremarkable, whereas magnetic resonance imaging showed 2 intramuscular fluid collections requiring surgically drainage.
A review of medical literature showed that pyomyositis is an infrequent complication in children with hematological malignancies, and most cases are due to Staphylococcus aureus, whereas Pseudomonas aeruginosa appears to be rarely involved.

摘要：
我们报告了一名11岁女孩的病例，该女孩最近诊断为常见的B细胞急性淋巴细胞白血病，该患者在与化疗诱导期相关的严重中性粒细胞减少症中出现左下肢铜绿假单胞菌化脓性肌炎。
表现出的症状包括发烧，腿部疼痛,拒绝走路。膝部超声检查无异常，而磁共振成像显示有2个需要手术引流的肌内积液。
医学文献综述显示，在儿童血液系统恶性肿瘤中，化脓性肌炎是一种罕见的并发症。大多数病例是由金黄色葡萄球菌引起的,而铜绿假单胞菌似乎很少涉及。
