We have reported the cases of two young patients who presented transient mutism in the course of recovery from removal of a cerebellar medulloblastoma. Although cerebellar symptoms were observed immediately after surgery, neither consciousness disturbance nor sensory aphasia was observed when the patients were mutic. From the analysis of serial magnetic resonance imaging (MRI). Gd-enhanced regions were noticed in the dentate nucleus and the cerebellar peduncle when mutism appeared, and they disappeared when mutism was gone. Although the mechanism of this interesting symptom is not clear, these MRI findings may indicate that focal ischemia or edema associated with surgical procedure may play a role in the appearance of this symptom.
我们报告了两名年轻患者的病例，他们在小脑髓母细胞瘤切除术后恢复过程中出现了短暂性缄默症。虽然术后立即观察到小脑症状，但患者缄默时既未观察到意识障碍也未观察到感觉性失语。通过对系列磁共振成像（MRI）的分析，发现缄默症出现时齿状核和小脑脚有钆增强区域，缄默症消失时这些区域也消失了。虽然这种有趣症状的机制尚不清楚，但这些MRI表现可能表明与手术相关的局灶性缺血或水肿在该症状的出现中起作用。
