A case of intermuscular lipoma in the perivertebral space

We describe our experience of a case of intermuscular lipoma located in the perivertebral space. The patient was a 48-year-old male who presented with the chief complaint of a right neck swelling, first noticed about two years earlier. Cervical ultrasonography and MRI revealed a tumorous lesion expanding into the perivertebral space. Intraoperatively, there were no adhesions between the lipoma and the surrounding tissue. Manual ablation of the lipoma was effective in the deep region, where the lipoma could not be visualized directly. We successfully accomplished complete resection of the lipoma without any serious complications. In the management of intermuscular lipomas expanding into the perivertebral space, surgical treatment should be considered, because resection can be accomplished with little risk of postoperative complications.
