20例肺结核合并肺癌患者的临床和影像学特征杨松 张耀亭 【摘要】 目的 总结肺结核合并肺癌的临床和影像学特点,提高诊断水平。
方法 回顾性收集2001年1月~2005年6月期间肺结核合并肺癌病例的临床资料。
结果 肺结核合并肺癌20例,大于60岁患者15例,中年患者5例。
陈旧性肺结核合并肺癌11例,进展期肺结核合并肺癌9例。
主要症状为刺激性咳嗽、痰血、低热、盗汗、气喘、消瘦、声嘶、胸痛等。
肺癌病灶发生于肺结核所在肺叶或肺段11例,发生癌变时间为3个月~10年。
癌变时肺部影像学主要表现为斑片影增多,空洞逐渐变大,洞壁厚薄不均匀,内缘不光滑、不规则、分叶、带毛刺的结节或肿块,可伴支气管狭窄、纵隔淋巴结肿大、肺不张,经纤维支气管镜、经皮肺穿刺或胸液等检查可同时发现癌细胞和抗酸杆菌证据。
结论 肺结核合并肺癌现象并不少见,对于陈旧性或进展期肺结核,临床症状加重,影像学导常变化,应高度怀疑肺结核合并肺癌可能,及时行相关辅助检查提高诊断水平。
