The purpose of this project is to investigate the clinical and brain MR characteristics of Epstein-Barr virus (EBV) encephalitis and encephalomyelitis. Clinical and 30 MR findings of 29 patients with EBV encephalitis or encephalomyelitis were retrospectively reviewed. Patients included 24 with encephalitis, 3 with encephalomyelitis, and 2 with brain-stem encephalitis. Altered consciousness, seizures, visual hallucination, and acute psychotic reaction were the common presentations. Eight patients had positive MR findings. These included T2 prolongation over gray and white matter, periventricular leukomalacia, and brain atrophy. Transient T2 prolongation over gray and white matter was found in one patient. Our results indicate that EBV encephalitis and encephalomyelitis have a wide range of both clinical and MR findings. The MR lesions may disappear in a short period, so the timing for the MR scan may be critical.
本项目旨在研究爱泼斯坦-巴尔病毒（EBV）脑炎和脑脊髓炎的临床及脑部磁共振成像（MR）特征。对29例EBV脑炎或脑脊髓炎患者的临床资料及30次MR检查结果进行回顾性分析。患者包括24例脑炎患者、3例脑脊髓炎患者和2例脑干脑炎患者。意识改变、癫痫发作、视幻觉和急性精神反应是常见表现。8例患者MR检查结果呈阳性。这些表现包括灰质和白质T2加权像信号延长、脑室周围白质软化和脑萎缩。1例患者出现灰质和白质短暂T2加权像信号延长。我们的结果表明，EBV脑炎和脑脊髓炎在临床和MR检查方面均有广泛表现。MR病变可能在短期内消失，因此MR扫描的时机可能至关重要。
