The ossifications of the transverse atlantal ligament taking the form of prominent osteophytes within atlas occur rarely.A computed tomographyexamination of the head in a 57-year-old man revealedthesignificantossifications ofthe transverse atlantal ligamentattachments. In the present study, the Osirix 3.9 MD system was employed to perform the bilateral evaluation of linear dimensions, projection surface area and volume of the theseossifications-osteophytes. The sagittal and transverse diameters of examined ossifications were: on the right side 4.02 and 3.97 mm, respectively, and on the left side 3.62 and 3.14 mm, respectively. Furthermore, on the right side the projection surface area and volume were: 12.03 mm2 and 27.66 mm 3 , respectively, and on the left side – 9.78 mm2 and 23.57 mm3 , respectively.Ossified attachments of the transverse ligament forming osteophytesseem to be casuistic.
