Chronic persistent pleural effusions were observed in 22 out of 140 patients with calcification involving the parietal and visceral pleurae. If no effusion is present, the two adjacent calcified pleurae may adhere together; and conversely, in the presence of fluid the pleural layers are separated, producing more than one linear density on the radiograph. Pleural thickening can exceed 2 cm. In patients with calcified fibrothorax, the calcified parietal pleura is separated from the inner thoracic wall by fat whether an effusion is present or not. The value of CT and sonography in the detection of persistent effusions is discussed.
在140例伴有壁层和脏层胸膜钙化的患者中，观察到22例存在慢性持续性胸腔积液。如果没有积液，相邻的两层钙化胸膜可能会粘连在一起；相反，存在液体时，胸膜层会分开，在X线片上产生不止一条线状密度影。胸膜增厚可超过2厘米。在纤维性胸廓钙化的患者中，无论有无积液，钙化的壁层胸膜与胸廓内壁之间均由脂肪分隔。本文讨论了CT和超声检查在检测持续性胸腔积液中的价值。
