AI Article Synopsis
- The report describes a patient with several rare anatomical variations of the atlas, including atlantooccipital assimilation (AS), anterior arch defect (AAD), and posterior arch defect (PAD), as seen through advanced CT imaging.
- The CT scans revealed specific deformities at the craniocervical junction, such as bilateral fusion between the atlas and occipital bone, and morphometric analysis suggested a risk of spinal cord compression.
- This case is notable because it documents an uncommon combination of these conditions, which has not been previously reported in medical literature.
Article Abstract
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.
