case_images: The lateral radiograph of his cervical spine showed characteristic flowing ossification along the anterior aspect of the cervical vertebrae from C2-C5, with relative preservation of the disc spaces (Figure 1).
case_images: The preoperative CT scan of the cervical spine reveals continuous but irregular flowing hyperostosis alongside the anterior aspect of the whole cervical vertebrae.. Abbreviation: CT, computed tomography.

case_images: The computed tomography scan of the cervical spine revealed continuous but irregular flowing hyperostosis alongside the anterior aspect of all the cervical vertebrae as well as local ossification of the posterior longitudinal ligament (Figure 2).
case_images: The axial CT scan shows outgrowth osteophytes covering the anterior side of the vertebrae as well as local ossification of the posterior longitudinal ligament.. Abbreviation: CT, computed tomography.

case_images: There were especially striking osteophyte outgrowths covering the anterior side of the vertebrae and projecting into the soft tissues of the neck from the level of C2 to C5 (Figure 3).
case_images: The preoperative T2-weighted sagittal magnetic resonance spin-echo image shows high signal intensity of bone marrow in C5-C7 as well as in the outgrowth hyperostosis.. Note: MRI did not show obvious spinal stenosis and cord compression.. Abbreviation: MRI, magnetic resonance imaging.

case_images: Sagittal T2-weighted magnetic resonance imaging showed bone marrow signal abnormality (high signal intensity) in C5-C7 as well as in the outgrowth hyperostosis (Figure 4).
