BACKGROUND
Heterotopic ossification (HO) is defined as ectopic bone formation following traumatic brain injury. Patients typically develop lesions in the hips, knees, and elbows that cause pain, restricted range of motion, nerve impingement, and pressure ulcers.
CASE REPORT
We report an unusual presentation of HO in an 18-year-old male who was involved in a motor vehicle accident and subsequently developed malignant intracranial pressure. His HO developed following bilateral craniectomies in which 2 different dural substitutes were used. Radiographic timing of ectopic bone formation and its continued growth varied.
CONCLUSION
We describe a case of HO in the cranium, a condition that is underreported in the literature. Of significance, despite sustaining multiple traumatic fractures that were managed conservatively, our patient failed to demonstrate any evidence of ectopic axial HO following his incident.
背景
异位骨化（HO）被定义为创伤性脑损伤后异位骨形成。患者通常在髋部、膝部和肘部出现病变，导致疼痛、活动范围受限、神经受压和压疮。
病例报告
我们报告了一名18岁男性的HO异常表现，该患者遭遇机动车事故，随后出现恶性颅内压。他的HO是在双侧颅骨切除术后发生的，术中使用了2种不同的硬脑膜替代物。异位骨形成的影像学时间及其持续生长各不相同。
结论
我们描述了一例颅骨HO病例，这种情况在文献中报道较少。重要的是，尽管患者遭受了多处保守治疗的创伤性骨折，但在事件发生后，我们的患者未显示出任何异位轴向HO的证据。
