A 52-year-old male presented with a brainstem abscess manifesting as high fever, diplopia, and left hemiparesis. Magnetic resonance (MR) imaging with gadolinium diethylenetriamine pentaacetic acid showed the lesion as a ring-like enhanced mass consisting of a necrotic center with surrounding edema, whereas postcontrast computed tomography revealed no such confirmatory findings. He was treated with antibiotics as the lesion had been detected in the acute cerebritis stage. Serial MR images showed that the lesion decreased remarkably in size. MR imaging can detect brain abscess in the earliest inflammatory stage.
一名52岁男性患者，表现为脑干脓肿，症状为高热、复视和左侧偏瘫。钆喷酸葡胺磁共振成像显示病灶为环状强化肿块，中央为坏死灶，周围有水肿，而增强计算机断层扫描未发现此类确诊表现。由于病灶在急性脑炎期被发现，故给予该患者抗生素治疗。系列磁共振图像显示病灶大小显著减小。磁共振成像能够在炎症最早阶段检测出脑脓肿。
