Talc pleurodesis is a technique used in the treatment of patients with persistent pleural effusions or pneumothorax not amenable to other treatment. These are commonly seen in patients with malignant thoracic neoplasms. Radiographic abnormalities resulting from prior talc pleurodesis could be confused with progression of the underlying neoplastic process. Positron emission tomography with F-18 fluorodeoxyglucose (FDG-PET) might be unable to distinguish between malignant and benign inflammatory processes. This report demonstrates the use of combined positron emission tomography/computed tomography (PET/CT) in a patient with a history of both malignant neoplasm and a prior talc pleurodesis. Fusion of PET and CT studies could add information that CT and PET alone cannot. This could alter the diagnostic and therapeutic course for patients with a history of both thoracic neoplasm and talc pleurodesis.
滑石粉胸膜固定术是一种用于治疗持续性胸腔积液或气胸且不适合其他治疗方法的患者的技术。这些情况常见于患有恶性胸部肿瘤的患者。先前滑石粉胸膜固定术导致的影像学异常可能与潜在肿瘤进程的进展相混淆。氟代脱氧葡萄糖F-18正电子发射断层扫描（FDG-PET）可能无法区分恶性和良性炎症过程。本报告展示了正电子发射断层扫描/计算机断层扫描（PET/CT）联合应用于一名既有恶性肿瘤病史又有先前滑石粉胸膜固定术病史的患者。PET和CT研究的融合可以提供单独的CT和PET无法提供的信息。这可能会改变既有胸部肿瘤病史又有滑石粉胸膜固定术病史患者的诊断和治疗过程。
