颅骨过度气化1例影像表现并文献复习

目的:颅骨过度气化(Craniocervical bone pneumatisation)比较少见,近年来对其报道和认识逐渐增多。本文介绍一例偶然发现的颅骨过度气化的影像表现并对相关文献进行复习。方法:分析我院1例颅骨过度气化的影像学图像。并从国外pubmed数据库(www.pubmed.gov)及国内中国知网数据库(www.cnki.net)查找发表的文献进行文献复习。结果:颅骨过度气化表现为颅骨的气腔形成并局部膨出,多为偶然发现或因并发症就诊,可涉及颅盖骨、颅底骨及颈椎等,近年来对其认识逐渐增多。结论:颅骨过度气化尽管少见,对征象的认知有助于相关科室医师正确识别此征象,从而有利于临床一些相关疑难病例的诊断和操作并对防止漏、误诊具有一定的意义。

Craniocervical Bone Pneumatisation: A Case Report and Review of the Literature*

Objective： Craniocervical bone pneumatisation is exceptionally rare, but there is a growing case reports of it from last century. Here we report one case of craniocervical bone pneumatisation which was diagnosised accidentally and presents the image result and review the literatures. Method： A 24-year-old male patient with craniocervical bone pneumatisation was found and his image results were reviewed. Also the literatures of craniocervical bone pneumatisation were retrieved and reviewed from pubmed library （www. pubmed.gov）and china knowledge resources library （www.cnki.net）. Result： Skull X-ray and head computed tomography （CT） scan were obtained from the case, and extensive pneumatization of right temporal bone, part of occipital bone and parietal bone were seen in this image data. Also, in brain window images of head CT, reduction in temporal and occipital lobe volume was observed in right cerebral hemisphere. In literatures, the main image manifestation of craniocervical bone pneumatisation is extensive pneumatization and local bulging of skull. This varies greatly between cases and involved in cranium, skull base and even the cervical vertebrae. The vast majority of cases were found by incidental examination or complications resulting from it. There is growing reports in the literature so far. Conclusion：The incidence of craniocervical bone pneumatisation seems to be very low. However, to some extent, the enhancement of knowledges in these will help physicians to make easier recognition of cases or some clinical procedure, to make right diagnosis for intractable cases and to prevent the leakage and the misdiagnosis in related field diseases under some situation in clinical practice.
