目的探讨婴幼儿自发性椎管内硬膜外血肿(SSEH)的临床影像特点,提高对该病的认识。方法回顾性分析本院2009年至2012年4例SSEH患者的临床影像资料。4例患儿临床表现均有肢体无力,全部病例均行MRI检查,2例行CT扫描。结果 4例SSEH血肿全部位于椎管脊髓背侧,病变范围超过5个椎体节段。颈胸段3例,胸段1例。血肿T1WI、T2WI均呈混杂低、高、等信号。结论婴幼儿当出现不明原因肢体无力时,需尽快完善MRI检查,排除SSEH。
Objective To investigate the clinical features of spontaneous spinal epidural hematoma (SSEH) in infants and young children and to improve their understanding of the disease. Methods The clinical data of 4 SSEH patients from 2009 to 2012 in our hospital were retrospectively analyzed. The clinical manifestations of 4 cases were both limb weakness, all cases underwent MRI examination, 2 cases of CT scan. Results All four SSEH hematomas were located in the dorsal aspect of the spinal canal, with lesions in more than 5 vertebral segments. Neck thoracic in 3 cases, thoracic in 1 case. Hematoma T1WI, T2WI were mixed low, high, and other signals. Conclusion Infants and young children when there is unexplained limb weakness, need to improve MRI examination as soon as possible, excluding SSEH.
