Pseudomyxoma Peritonei Lesion of the Thoracic Spine: A Case Report and Literature Review

Background: Pseudomyxoma peritonei (PMP) is a rare condition, with no previously described location in the spine. Here is presented a case of PMP extension to the thorax and then the spine, treated with two-level vertebrectomy, laminectomy, and posterior fusion. Case Report: We report here the case of a 64-year-old man presenting pathological fractures of T6 and T7 due to PMP extension to the pleural cavity and thoracic spine. He presented interscapular pain with mild spinal cord compression symptoms. He was treated by achieving T5-T8 laminectomy, T2-T10 pedicle fixation, and T6-T7 vertebrectomy. The postoperative course was uneventful apart from a pulmonary embolism (PE) with favorable evolution under anticoagulants. Conclusion: To achieve spinal cord decompression, kyphosis correction, and spine stabilization, a two-level vertebrectomy, laminectomy, and posterior fusion would be beneficial for a PMP lesion of the thoracic spine.
