A case of chondrosarcoma with costovertebral location in the posterior mediastinum: Resection and stabilization

Abstract

Chondrosarcoma, a primary malignant bone tumor, rarely occurs in the vertebrae. We report a 29-year-old female with a 6 × 4.2 cm chondrosarcoma in the posterior mediastinum originating from the left 9th costa vertebral junction involving vertabrea corpus. Surgical resection performed involving posterior thoracotomy, 8–9th rib resection, 8–9th thoracal vertebrae partial corpectomy, laminectomy, spinal instrumentation, and chest wall stabilization. Pathology confirmed chondrosarcoma with safe margins. The patient remained recurrence-free for 9 years. This case highlights the importance of wide-margin surgical resection and multidisciplinary approaches for long-term survival in chondrosarcoma patients.
