临床轻度脑炎/脑病伴可逆性脾病变(MERS)是一种临床放射综合征,诊断为该区域的暂时性高强度病变,包括call体的脾,扩散加权成像和神经精神症状恢复无后遗症。MERS在成年人中很少见,尤其是老年人。我们在此报告一名60多岁的男子被诊断患有军团菌肺炎引起的MERS。尽管有高龄的危险因素,但仅服用左氧氟沙星和阿奇霉素即可完全康复,未经治疗的高血压病史,双侧自发性气胸,吸烟和饮酒习惯和肺气肿。据我们所知,这是由于军团菌肺炎引起的最古老的MERS病例,在所有MERS病例中年龄极高。我们的研究表明,军团菌是成人发作的MERS最常见的病原体,而病毒是儿童的主要致病因素。这种情况有助于澄清高危成年人中MERS的特征。
Clinically mild encephalitis/encephalopathy with a reversible splenial lesion (MERS) is a clinicoradiologic syndrome diagnosed by temporary hyperintense lesion in the area, including the splenium of the corpus callosum, on diffusion-weighted imaging and neuropsychiatric symptoms that recover without sequelae. MERS is rare in adults, especially elderly people. We herein report a man in his 60s diagnosed with MERS caused by Legionella pneumonia. He completely recovered with only the administration of levofloxacin and azithromycin despite the risk factors of an advanced age, medical history of untreated hypertension, bilateral spontaneous pneumothoraxes, smoking and drinking habits and pulmonary emphysema. To our knowledge, this is the oldest
case of MERS due to Legionella pneumonia and extremely old among total MERS cases. Our research revealed that Legionella species are the most common pathogens of adult-onset MERS, while viruses are the main causative factors in children. This
case helps clarify the features of MERS in high-risk adults.
