摘要

简介在儿童时期,这些缝合线会闭合,形成头骨特有的缝合线,其中之一就是额缝,它将两块额骨完美地连接在一起,模拟出一块额骨。然而,这种缝合可能会持续到成年,形成一种解剖学上的变异,被称为 "偏头畸形"(metopism)。病例报告:一名 19 岁的墨西哥男性因骑摩托车时未戴安全头盔发生交通事故,造成高能量创伤。根据 Master 分类、进行性头痛、存在血肿和面部损伤,考虑进行简单头颅计算机断层扫描(CT),因为存在创伤性脑损伤(TBI)的中等风险因素。在进行简单颅骨断层扫描时,观察到偏头缝持续存在。结论在对人群进行调查研究时,偏头痛通常是作为死后发现的。本报告之所以受到特别关注,是因为它被确定为脑外伤后颅骨骨折的鉴别诊断。将陨石缝与骨折相鉴别的重要发现是边缘有锯齿状和硬化。通过前正位X光片可以很容易地诊断出持续性偏位缝合。

Metopism: An anatomical variant that the physician should take into account
Introduction: During childhood these sutures close, forming the characteristic sutures of the skull, one of these is the frontal suture, which joins the two frontal bones perfectly, simulating a single frontal bone. However, this suture can persist into adulthood, giving an anatomical variant known as metopism. Case Report: A 19-year-old Mexican male presented with high-energy trauma related to a traffic accident while riding a motorcycle without wearing a safety helmet. A simple skull computed tomography (CT) was considered due to moderate risk factors for traumatic brain injury (TBI), based on the Master’s classification, progressive headache, presence of hematoma, facial injuries. When performing the simple skull tomography, persistence of the metopic suture was observed. Conclusion: Metopism has generally been reported as a postmortem finding in population studies aimed at its search. This report has special attention because it was identified as a differential diagnosis of a skull fracture following a traumatic brain injury. The important finding that differentiates metopic suture from a fracture is the presence of serrated and sclerotic edges. A persistent metopic suture can be easily diagnosed by an anteriorposterior radiograph.
