A 77-year-old man presented with progressive consciousness disturbance, presumably caused by a backward fall. Head computed tomography findings showed a large intracerebral hemorrhage in the left parietal lobe. Radiated fractures with an oval depression of the bilateral parietal bone crossing the midline were noted. Surgical evacuation of the hemorrhage was performed via a left-sided parietal craniotomy, during which fragments from the fracture with eggshell-like thinning were noted. Biparietal thinning is an uncommon condition noted in radiological findings of a symmetrical oval depression of bilateral parietal bones with reduced diploe thickness. Cases of traumatic brain injury in patients with biparietal thinning have rarely been reported. This condition should be recognized as a possible predisposing factor for traumatic brain injury.
一位 77 岁男性因向后摔倒导致进行性意识障碍就诊。头部计算机断层扫描结果显示左顶叶有大量颅内出血。放射状骨折伴双侧顶骨中线处椭圆形凹陷，颅骨变薄。通过左侧顶骨开颅手术清除血肿，术中发现骨折碎片呈蛋壳样变薄。双顶骨变薄是一种罕见的影像学表现，表现为双侧顶骨对称性椭圆形凹陷，板障厚度变薄。双顶骨变薄患者外伤性脑损伤的病例很少有报道。这种情况应被认为是外伤性脑损伤的一个可能的诱发因素。
