目的：报告滑石粉胸膜固定术治疗自发性胸腔积液患者的CT表现。材料和方法：回顾了5年内获得的16例患者的胸膜固定术后CT研究。平均年龄为63岁（范围41-79岁）。10例患者死亡。胸膜固定术后，9例患者进行了一个单一的胸部CT检查，7例患者进行了一个以上的。结果：在所有患者中观察到的特征性发现，除了一个，是胸膜腔的后基底区域存在高密度存款。7例患者的这些病变通常为线性，2例为结节性，6例为线性和结节性的组合。在5名患者中，两个内脏上均存在滑石粉沉积物。壁层胸膜被积液分开（胸膜分裂征的一种变体）。滑石粉沉积物扩展到叶间裂与相关的裂隙增厚5例。在接受了一个以上的CT研究的患者，外观保持stabilis.CONCLUSIONS：典型的发现是存在于胸膜腔的后基底区域的高衰减区。观察到两个新的外观：滑石粉沉积物延伸到裂缝和存在一个变异的分裂胸膜迹象。重要的是要认识到这些CT表现，以免与石棉暴露等其他情况混淆。(c)2006年皇家放射科医师学院。由爱思唯尔有限公司出版。保留所有权利。
AIM: To report the computed tomography (CT) appearances of talc pleurodesis in the management of patients with pleural effusions and spontaneous. pneumothorax.MATERIALS AND METHODS: The post-pleurodesis CT studies of 16 patients obtained over a 5-year period were reviewed. The mean age was 63 years (range 41-79 years). Ten patients were mate. After pleurodesis, nine patients underwent a single chest CT examination and seven patients underwent more than one.RESULTS: The characteristic finding observed in all patients, except one, was the presence of high-density deposits in the posterior basal regions of the pleural space. These were typically linear in seven patients, nodular in two, and a combination of linear and nodular in six. In five patients talc deposits were present on both the visceral. and parietal pleura separated by an effusion (a variant of the split pleura sign). Talc deposits extended into an interlobar fissure with associated fissural thickening in five patients. In patients who underwent more than one CT study, the appearances remained stable.CONCLUSIONS: The typical finding was the presence of high attenuation areas in the posterior basal regions of the pleural space. Two new appearances were observed: extension of talc deposits into the fissure and the presence of a variant of the split pleura sign. It is important to recognize these CT appearances so as not to confuse them with other conditions such as asbestos exposure. (c) 2006 The Royal College of Radiologists. Published by Elsevier Ltd.
