Leukemia is the most frequent malignancy in children (30-40%); acute lymphoblastic leukemia (ALL) accounts for 85% of cases of this leukemia. Apart from bone marrow infiltration, MR imaging reveals other lesions in the bones of these children, that may be a complication of the disease or of its therapy and do not require referral to the oncologist unless they are misinterpreted. These lesions include osteonecrosis, stress fractures due to osteopenia, osteomyelitis - often resulting from administration of corticosteroids. The authors present MR images of these lesions, often misinterpreted as leukemic infiltration.
白血病是儿童中最常见的恶性肿瘤（占30%-40%）；急性淋巴细胞白血病（ALL）占此类白血病病例的85%。除骨髓浸润外，磁共振成像（MR）还显示这些儿童骨骼中的其他病变，这些病变可能是疾病本身或其治疗的并发症，除非被误诊，否则无需转诊给肿瘤学家。这些病变包括骨坏死、骨质减少导致的应力性骨折、骨髓炎——通常由使用皮质类固醇引起。作者展示了这些常被误诊为白血病浸润的病变的MR图像。
