A patient with paraquat poisoning was followed up for five years, and it was showed that the interstitial lesion areas in chest CT of this patient gradually decreased after acute period of the poisoning and no significant changes were found six months later. After that the density of the lesions gradually reduced, while the cystic air cavities slowly increased. In addition, the patient's exercise endurance gradually improved over time, and the lung function was close to the normal level five years after poisoning. The follow-up report helps clinicians to have a deeper understanding of the long-term outcome of paraquat poisoning.
我们对1例百草枯中毒患者进行长达5年的随访，胸部CT发现该患者肺间质病变范围随时间推移逐渐缩小并于中毒后6个月不再明显变化，其后病变区密度逐渐降低，并可见缓慢增多的囊性气腔。随时间推移，该患者运动耐力逐渐提高，中毒后第5年检查肺功能已接近正常水平。本例随访报道有助于临床医师对百草枯中毒的远期转归产生更深入的了解。.
