MRI of a rare case of polyneuritis following brucellosis is presented. An 8-year-old boy with a history of brucellosis showed marked enlargement of the origin of the left fifth cranial nerve and contrast enhancement of the fifth cranial nerves and the Gasserian ganglion in Meckel's caves. A well-defined low-signal cystic mass showing peripheral contrast enhancement lay anteromedial to the left seventh and eighth cranial nerves. The seventh and eighth nerves showed marked enhancement. The prechiasmatic portion of the right optic nerve showed fusiform enlargement with marked contrast enhancement of the nerve and right optic tract. MRI immediately after treatment showed no enhancement of the cranial nerves. Enlargement of the origin of the left fifth cranial nerve persisted, but there was no enlargement of the optic nerve. The mass near the left seventh and eighth cranial nerves was still present with no obvious morphological change, but no longer showed peripheral enhancement.
本文介绍了1例布鲁氏菌病后多发性神经炎的罕见病例的磁共振成像（MRI）表现。一名有布鲁氏菌病病史的8岁男孩，其左侧第五颅神经起始部明显增粗，第五颅神经及位于梅克尔腔的三叉神经节有强化。一个边界清晰的低信号囊性肿物位于左侧第七、八颅神经前内侧，周边有强化。第七、八颅神经强化明显。右侧视神经视交叉前部分呈梭形增粗，神经及右侧视束强化明显。治疗后即刻MRI显示颅神经无强化。左侧第五颅神经起始部增粗仍然存在，但视神经无增粗。左侧第七、八颅神经附近的肿物仍然存在，形态无明显改变，但不再有周边强化。
