An Atypical Presentation of Radiation-Induced Enteritis Treated With Hyperbaric Oxygen Therapy

Delayed radiation-induced injuries generally manifest months to years after the completion of radiation therapy and can be challenging to diagnose and treat because of a paucity of evidence-based therapeutic options. Individuals who receive high doses of radiation therapy are more likely to experience delayed radiation injuries, but those who receive relatively low radiation doses may also rarely develop this condition. We present the case of a patient who developed delayed radiation-induced enteritis several weeks after receiving low-dose radiation therapy to the terminal ileum. The patient's signs and symptoms improved significantly after administration of hyperbaric oxygen therapy.
