【摘要】 放射性肺炎(RP)是胸部肿瘤经放射治疗后，在肺部放射野内受到损伤而引起的炎症反应，其中快速进展型则是一种较为严重的类型，其通常在放射治疗后较短时间内(4～12周)迅速进展，表现为严重的肺部炎症和纤维化。快速进展型RP的早期阶段不易发现，晚期发现时往往又预后不佳，甚至导致呼吸衰竭、死亡。该文报道了1例快速进展型RP,以期为该疾病的早期诊断、预测和治疗提供参考。更多还原

【Abstract】 Radiation pneumonitis(RP) is an inflammatory response caused by damage to the lung radiation field after radiation therapy for chest tumors.Among them, the rapidly progressing type is a more serious type, which usually progresses rapidly within a short period of time(4-12 weeks) after radiation therapy, manifested as severe lung inflammation and fibrosis.The early stages of rapid progressive RP are difficult to detect, and when discovered in the late stages, the prognosis is often poor, even leading to respiratory failure and death.The article reports a case of rapidly progressing RP,aiming to provide reference for early diagnosis, prediction, and treatment of the disease.更多还原
