摘要
目的探讨有机氟中毒性肺水肿的CT诊断价值。方法回顾性分析本院收治的有机氟中毒3例,分析其临床和CT表现。结果中毒性肺水肿是有机氟中毒的主要损伤,CT主要表现为肺内团絮状影伴磨玻璃影,病变愈重密度愈高;胸腔积液;纵隔、皮下气肿。肺内病变吸收时先是密度降低,逐渐呈磨玻璃影,最后才范围缩小,直至完全吸收。经正确积极治疗肺内病变和胸腔积液可在60-72h吸收;纵隔、皮下气肿需6d以后吸收。结论CT对有机氟中毒性肺水肿早期诊断和恢复期评价、并发症的发现具有重要意义,同时也对职业性损伤的鉴别诊断具有重要价值。
Objective To investigate CT diagnosis values of pulmonary edema induced by organoflurine. Methods The clinical data and CT features were retrospectively analyzed in 3 cases of pulmonary edema induced by organoflurine. Results Pulmonary edema was main injury in organoflurine poisoning. CT scans revealed patch shadows with ground-glass opacities in both lungs, more serious in pathological changes, more high in focus＇s density. They had pleural effusion, mediastinal and subcutaneous emphysema. After correct treatment, pathological changes in lung and pleural effusion could absorb in 60-70 hours. Mediastinal and subcutaneous emphysema could absorb after 6 days. Conclusion CT has great value in early diagnose, evaluation of recover stage, findings of complications and differential diagnosis of pulmonary edema induced by organoflurine.
