Four lumbar segments were found with ossified anterior longitudinal ligaments from L3 to S1 with fractured ossified ligaments at the level of L3/L4 (Figure 1, case 4).
(A) Schematic illustration of Andersson-like lesions (ALLs) in diffuse idiopathic skeletal hyperostosis (DISH). The ALLs were classified as transdiscal (left), transvertebral (middle), or discovertebral (right) lesions in the DISH spine. (B-D) Postoperative radiographs for case 1 (B), case 3 (C), and case 4 (D). Case 2 underwent conservative treatment, which included pharmacologic and corset interventions, due to respiratory and circulatory problems.
