Abstract

Radiation induced brachial plexopathy (RIBP) is an unfortunate complication of radiation involving the axilla and supraclavicular fossa. This case report highlights development of RIBP in a patient 15 years after initial radiation and 11 years after pulsed low dose rate (PRDR) re-irradiation for recurrent disease. PRDR is a radiation technique believed to lower normal tissue toxicity due to improved sublethal intrafraction damage repair of these tissues at low radiation dose rates with good reported long term locoregional control in the re-irradiation setting. However, RIBP, as seen in this patient, is a devastating side effect of high dose radiation to this region, with no effective treatment options outside of symptom management and control. In this case, the patient has remained disease free following her recurrence but has had continued RIBP with minimal improvement using pentoxyfilline for management.
