摘要

虾米征的特征是小脑深部白质出现界限清楚的病变，T2-加权成像信号高强，T1-加权成像信号低强，单侧或双侧与齿状核毗邻并勾勒出齿状核的轮廓。在正确的临床情况下，这一征象对小脑进行性多灶性白质脑病（PML）具有较高的敏感性和特异性。在本文中，我们介绍了一例小脑PML病例，患者是一名女性人类免疫缺陷病毒感染者，未接受抗逆转录病毒治疗，在脑部核磁共振成像中出现虾状征象。

I saw the “shrimp sign”: Cerebellar progressive multifocal leukoencephalopathy

The shrimp sign is characterized by a well-defined lesion in the deep cerebellar white matter, with hyperintense signal on T2- and hypointense signal on T1-weighted imaging, abutting and outlining the dentate nucleus, unilaterally or bilaterally. This sign has high sensitivity and specificity for cerebellar progressive multifocal leukoencephalopathy (PML) within the correct clinical scenario. In this article, we present a case of cerebellar PML in a woman living with human immunodeficiency virus, who was not using antiretroviral therapy, and presented the shrimp sign on brain MRI.

期刊介绍： The mission of Clinical Imaging is to publish, in a timely manner, the very best radiology research from the United States and around the world with special attention to the impact of medical imaging on patient care. The journal''s publications cover all imaging modalities, radiology issues related to patients, policy and practice improvements, and clinically-oriented imaging physics and informatics. The journal is a valuable resource for practicing radiologists, radiologists-in-training and other clinicians with an interest in imaging. Papers are carefully peer-reviewed and selected by our experienced subject editors who are leading experts spanning the range of imaging sub-specialties, which include: -Body Imaging- Breast Imaging- Cardiothoracic Imaging- Imaging Physics and Informatics- Molecular Imaging and Nuclear Medicine- Musculoskeletal and Emergency Imaging- Neuroradiology- Practice, Policy & Education- Pediatric Imaging- Vascular and Interventional Radiology
