摘要
在本报告中，一名性别和年龄不详的患者通过计算机断层扫描（CT）发现了寰枕同化（AS）、寰枕前弓缺损（AAD）、寰枕后弓缺损（PAD）以及颅颈交界处的一些变异。冠状和矢状CT扫描显示寰椎和枕骨基部有强直性脊柱炎和双侧融合。寰椎的轴向 CT 扫描显示左侧为 PAD B 型，中线为 AAD。形态测量显示脊髓腹侧可能受到压迫。此外，中矢状面 CT 显示右侧存在舟状窝和横突孔未完全形成。本研究报告了一例极其罕见的伴有AAD、PAD以及其他颅楔和寰椎变异的强直性脊柱炎。据我们所知，文献中还没有类似病例的报道。
Atlantooccipital assimilation associated with combined atlas arch defect: a radiological case report.
In this report, atlantooccipital assimilation (AS), anterior arch defect (AAD), and posterior arch defect (PAD) of the atlas, and several variations around the craniocervical junction were identified on computed tomography (CT) of a patient of unknown sex and age. Coronal and sagittal CT scans showed AS and bilateral fusion of the atlas and the base of occipital bone. Axial CT scan at the atlas revealed PAD type B on the left side and midline AAD. Morphometric measurements indicated a potential ventral spinal cord compression. In addition, mid-sagittal CT revealed the presence of fossa navicularis magna and incomplete formation of the transverse foramen on the right side. This study reports an extremely rare AS associated with AAD, PAD, and other variations of the clivus and the atlas. To our knowledge, no similar case has been reported in the literature.
