Abstract

We present clinical and magnetic resonance (MR) findings in 83 patients with inner cerebral trauma (ICT). In addition to the ICT-related lesions, uni- or bilateral enlargement and signal abnormalities of the inferior olivary nucleus were detected by MR in 9.6% of patients as a consequence of lesions within the dentato-rubro-olivary pathway. Clinically, segmental myoclonias were present in five patients. These observations suggest that MR imaging is highly sensitive in the detection of olivary hypertrophy and of causative traumatic lesions of the dentato-rubro-olivary pathway.

摘要

我们展示了83例脑内创伤（ICT）患者的临床和磁共振（MR）检查结果。除了与ICT相关的病变外，MR检查在9.6%的患者中检测到因齿状红核橄榄束通路内病变导致的单侧或双侧下橄榄核增大及信号异常。临床上，5例患者出现节段性肌阵挛。这些观察结果表明，MR成像在检测橄榄核肥大及齿状红核橄榄束通路的创伤性致病病变方面具有高度敏感性。
