Abstract
Restricted water diffusion has been used to distinguish pyogenic abscess from other rim-enhancing brain masses; however diffusion-weighted imaging of cerebral infection before capsule formation has rarely been described. We report a case of fungal cerebritis in which water diffusion was more restricted than that of normal contralateral brain and the measured diffusion coefficient was in the range of that reported for pyogenic brain abscess. In the proper clinical setting, cerebritis should be considered in the differential diagnosis of an ill-defined focal brain mass associated with markedly restricted water diffusion.
摘要
受限水扩散已被用于区分化脓性脓肿与其他环形强化脑肿块；然而，关于包膜形成前脑感染的扩散加权成像却鲜有描述。我们报告一例真菌性脑炎病例，其水扩散比正常对侧脑更受限，且测得的扩散系数处于化脓性脑脓肿报道的范围内。在适当的临床情况下，对于与明显受限水扩散相关的边界不清的局灶性脑肿块进行鉴别诊断时，应考虑脑炎。
