ac Representative case of the posterior-vertebral type. a CT image: The ligament remained nearly unchanged with regard to thickness and surface area. Localized high-density areas were observed along the longitudinal axis in the PLL. b Three dimensional reconstruction image: High-density areas were without continuity with the vertebra. c Pathological image: This type showed isolated calcifying foci characterized by a linear-shaped, stereoscopically plate-shaped calcification and/or ossification in the PLL developed just behind the vertebral body
