Treatment of a malignant peripheral nerve sheath tumor and its complications through a multidisciplinary approach

Abstract

The authors report the case of a 14-year-old girl with a residual malignant peripheral nerve sheath tumor after thoracotomy, chemotherapy, and radiation therapy. The residual tumor, which involved the intercostal muscles, aorta, and neural foramina of T4-10, was completely resected through a costotransversectomy and multiple hemilaminotomies with the patient in the prone position and was stabilized using a T1-12 pedicle screw fusion. Postoperatively, the patient developed several infections requiring multiple washouts and prolonged antibiotics. Thirty months after surgery, she developed a bronchocutaneous fistula. The hardware was removed, and a vascularized latissimus dorsi free flap was placed over the lung. She continued to have an air leak and presented 3 weeks later with a 40° left thoracic curve. She returned to the operating room for a T2-L2 fusion with a vascularized fibular graft. On postoperative Day 1, she underwent a bronchoscopy and had her left lower lobe airways occluded with multiple novel one-way endobronchial valves. She is now 5 years out from her tumor resection and 3 years out from her definitive fusion. She has no evidence of residual tumor, infection, or pseudarthrosis and continues to remain asymptomatic.
