Abstract:
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.
摘要:
一名77岁的男子出现了进行性意识障碍,大概是由倒退引起的。头部CT检查结果显示左顶叶有大量脑出血。注意到放射状骨折,双侧顶骨的椭圆形凹陷穿过中线。通过左侧顶骨开颅术进行了出血的外科清除,在此期间,发现了卵壳状变薄的骨折碎片。在放射学发现的双侧顶骨的对称椭圆形凹陷,双顶变薄是一种罕见的情况,双顶厚度减小。很少报道双顶变薄患者的创伤性脑损伤病例。这种情况应被认为是创伤性脑损伤的可能诱发因素。
