摘要
目的 探讨副肿瘤性边缘叶脑炎(PLE)的临床和影像学特征。方法 报告2例PLE患者(分别合并侵袭性胸腺瘤及肺癌)的临床、实验室及影像学资料。结果 2例均有癫癎发作、记忆及定向障碍、明显精神异常。头颅MRI均表现为颞叶海马长T_1、长T_2信号。1例在急性期脑部正电子发射扫描(PET)表现为病灶部位放射性浓集。结论 临床表现及影像学检查是诊断PLE的重要手段。
Objective To study the clinical and imaging features of paraneoplastic limbic encephalitis (PLE). Methods The clinical, latoratorial and imaging information of two patients with clinically diagnosed PLE associated with invasive thymoma or lung cancer are reported. Results Two cases had typical findings in clinical symptoms ( severe neuropsychological deficits, disorientation, memory impairment and seizures) and MRI showed ( abnormal high-signal intensity in hippocampal formations and temporal lobe on T2-weighted imagings) , One patient was investigated by cerebral 18 F-fluoro-2-deoxy-D- glucose- positron emission tomography (FDG-PET) , and highly significant focal hypermetabolism in bilateral temporal and other areas was found. Conclusion The clinical and imaging examination are the improtant method for the diagnosis of PLE.
