IntroductionSoft tissue and bone radionecrosis are rare but serious complications may occur late after radiotherapy.Case reportWe report the case of an 86-year-old woman with a history an infiltrating ductal carcinoma of the left breast, treated by total mastectomy, left axillary dissection and adjuvant radiotherapy. Eighteen years later, the first radionecrosis lesions appeared and grew progressively in a 6-month period. These lesions are deep, involving the anterior aspect of the 4th to the 6th ribs and infiltrating the chest wall to the left cardio-thoracic space communicating largely with the pericardium. During axillary dissection, the neurovascular pedicle of the left latissimus dorsi muscle had been severed. The first part of the operation consisted of performing a left side parietectomy of the thoracic wall with a large resection of pericardial tissue and a small myocardial patch. The second step consisted of repairing the thoracic wall defect with a contralateral musculocutaneous latissimus dorsi flap.ConclusionDue to its significant axis of rotation, the latissimus dorsi muscle flap must be considered in the therapeutic algorithm for covering of contralateral anterior chest wall defects.
