Abstract

Scrub typhus is an acute febrile illness caused by Orientia tsutsugamushi. The diagnosis of scrub typhus relies on the patient's history of exposure, clinical manifestations, and results of serological tests. Our patient had a history of altered sensorium, inability to walk, and macular rashes predominantly distributed over the chest and bilateral upper limbs. Post serological testing, the patient was referred to the radiology department for MRI brain. Radiologically, MRI being a superior modality helps in the evaluation of lesions in depth, helping to simplify the diagnosis of meningitis, scrub typhus encephalitis, and other related conditions. Various findings have been described in scrub typhus encephalitis in MR brain imaging, and our case shows an unusual finding in brain imaging.

摘要

恙虫病是由恙虫东方体引起的急性发热性疾病。恙虫病的诊断依赖于患者的暴露史、临床表现和血清学检测结果。我们的患者有精神状态改变、无法行走和斑丘疹,主要分布在胸部和双侧上肢。血清学检测后,患者被转至放射科行脑部 MRI 检查。影像学上,MRI 作为一种优越的检查方式有助于评估病变的深度,有助于简化脑膜炎、恙虫病脑炎和其他相关疾病的诊断。在脑 MRI 影像中已经描述了恙虫病脑炎的各种发现,我们的病例显示了一种不常见的脑部影像学发现。
