Radiation-induced rib fractures (RIRF) are long-term complications associated with irradiation of the chest/chest wall. RIRFs are commonly seen in lung- or breast-cancer patients treated with stereotactic body radiotherapy (SBRT) or conventional external beam radiation therapy (EBRT), respectively. We report a case of a 31-year-old female presenting with pathological fractures of the third, fourth, and fifth ribs discovered on magnetic resonance imaging (MRI) as a complication from pencil beam scanning (PBS) proton therapy (PT), of the whole left breast and regional lymph nodes. To our knowledge, this presentation is the first to be initially reported on MRI in radiological literature.
放射性肋骨骨折（RIRF）是胸部/胸壁放疗相关的长期并发症。RIRF常见于分别接受立体定向体部放疗（SBRT）或传统外照射放疗（EBRT）治疗的肺癌或乳腺癌患者。我们报告一例31岁女性病例，其在磁共振成像（MRI）检查中发现第三、第四和第五肋骨病理性骨折，这是全左侧乳腺及区域淋巴结笔形束扫描（PBS）质子治疗（PT）的并发症。据我们所知，该病例表现是放射学文献中首次在MRI上最初报告的。
