Encephalocele is a rare condition that consists of herniation of cerebral matter through openings of dura and skull. A majority of encephaloceles are congenital and manifest in childhood. We present a case of a 45-year-old man presenting with contralateral hemiparesis and found to have an extremely rare phenomenon of a symptomatic posttraumatic parietal intradiploic encephalocele (IE) manifesting 36 years following pediatric traumatic head injury. Computed tomography and magnetic resonance imaging confirmed herniation of brain tissue into the intradiploic space. Surgical treatment with reduction of the encephalocele achieved near resolution of preoperative hemiparesis on follow-up. The pathogenesis and a literature review of IE are discussed.
脑膨出是一种罕见的病症，由脑实质通过硬脑膜和颅骨的开口疝出组成。大多数脑膨出是先天性的，在儿童期表现出来。我们报告一例45岁男性，表现为对侧偏瘫，发现其患有一种极其罕见的现象，即小儿创伤性脑损伤36年后出现有症状的创伤后顶骨板障内脑膨出（IE）。计算机断层扫描和磁共振成像证实脑组织疝入板障内间隙。通过手术治疗使脑膨出复位，随访时术前偏瘫几乎完全缓解。本文讨论了IE的发病机制并进行了文献综述。
