A sixty-seven year old
male was treated with palliative
radiation therapy due to his right
hip joint pain, and the
pain was caused by osteolytic right acetabular
metastasis. He underwent 30 Gy irradiation and then his painful symptoms disappeared at the 1 month follow-up after
radiation therapy. He next received received systemic
chemotherapy with 3 cycles of
gemcitabine plus
cisplatin and then 6 cycles of
docetaxel. He visited the
emergency room at the
time of 4 months after the completion of
radiation therapy with complaints of relapsed right
hip joint pain. On MRI, localized muscular swelling with infiltration and without contrast-enhancement was seen within the previous
radiation field, and the clinical impression was
radiation-recall
myositis. We provided symptomatic
treatment and his right
hip joint pain with disability disappeared 2 weeks after the
treatment. No
relapse of the right
hip joint pain developed during the
patient's
survival period. We experienced a case of
radiation-recall
myositis that was related to
gemcitabine use after
radiation therapy
