传染性单核细胞增多症(infectious mononucleosis,IM)由EB病毒(Epstei-barr,EBV)感染所致的单核-巨噬细胞系统急性增生的感染性疾病,小儿常见,通常病程有自限性。临床上以发热、咽峡炎、淋巴结及肝脾肿大、外周血中淋巴细胞增加并出现异型淋巴细胞等为特征。但由于EBV感染疾病谱广泛、感染相关的IM可有不典型表现、实验室结果的时间及年龄相关性限制,早期常见误诊。本文分析总结常见IM误诊及原因,以期达到早期诊断的目的。
Infectious mononucleosis (IM) Infectious diseases of acute monocytic-macrophage system caused by Epstein-Barr (EBV) infection are common in children and usually have a limited duration of disease . Clinically, fever, angina, lymph nodes and hepatosplenomegaly, increased peripheral blood lymphocytes and the emergence of atypical lymphocytes and other features. However, due to the broad spectrum of EBV-infected diseases, infection-related IM may have atypical manifestations, laboratory results of time and age-related limitations, and early misdiagnosis. This article analyzes and summarizes the common misdiagnosis and reasons, in order to achieve the purpose of early diagnosis.
