Radiation Recall Myositis Detected With 18F-FDG PET/CT After a Treatment of Cervical Cancer.

A 34-year-old woman, after being treated for cervical cancer, presented with severe pain in the inguinal and the upper abdominal region with restriction in range of motion of the trunk 71 days after radiation therapy and 19 days after receiving adjuvant gemcitabine and cisplatin chemotherapy. The F-FDG PET/CT showed complete response to cancer treatment, but also revealed a localized inflammatory process that was delimited by radiation fields rather than anatomical structures, suggesting a radiation recall phenomenon.
