He was addressed to our department in 2020 suffering from lumbar-radicular pain and functional impotence of both lower limbs. MRI was performed showing multiple big cysts with inhomogeneous contents. CT scan showed destruction of the l5 vertebra. The patient underwent surgery. Initially, we performed through a posterior approach, an L4 to S1 laminectomy, posterior stabilization, and then total L5 corpectomy, anterior l4-s1 fusion through a xipho-pubic laparotomy after 2 months.
