Brain MR imaging abnormalities in primary Sjögren syndrome (pSS) are generally discrete white matter lesions. We describe a 50-year-old woman with recurrent neurologic deficits. MR imaging revealed a large brain lesion. A diagnosis of pSS was made on the basis of clinical features, positive anti-Ro and anti-La antibodies, abnormal Schirmer test findings, and salivary gland scintigraphy. The patient was treated with oral prednisone with good response. Large tumefactive brain lesions are a complication of pSS.
原发性干燥综合征(pSS)的脑部磁共振成像异常通常为散在的白质病变。我们描述了一名50岁复发性神经功能缺损的女性。磁共振成像显示一个大的脑部病变。根据临床特征、抗Ro和抗La抗体阳性、泪液分泌试验结果异常以及唾液腺闪烁扫描,诊断为pSS。该患者接受口服泼尼松治疗,反应良好。巨大肿块性脑部病变是pSS的一种并发症。
