Abstract

Management of soft tissue sarcomas is often complicated, requiring radiation before and in some cases after limb-sparing surgery. Radiation necrosis is a severe complication after radiation treatment and is typically dose related and involves medullary bone. We report on two cases of hitherto unreported focal circumscribed intra-cortical lytic lesions within the radiation portal, which appeared 19 months and 31 months, respectively, after the conclusion of radiation treatment. Both patients had a history of soft tissue sarcoma treated with radiation (66 Gy) and surgical resection. Biopsy of these lesions showed necrotic bone attributed to radiation.
