肺气囊(pneumatocele)(图文)

病理学表现 :为肺内薄壁的充气气腔。常为急性肺炎、外伤、吸入碳氢化合物液体所致,常为一过性。发病机制是实质坏死和活瓣性气道阻塞的综合作用。 4pL影像园XCTMR.com X 线胸片和CT 表现 : 肺气囊表现为肺内近圆形的薄壁气腔。 4pL影像园XCTMR.com Patho

Pathology.—A pneumatocele is a thin-walled, gas-filled space in the lung. It is most frequently caused by acute pneumonia, trauma, or aspiration of hydrocarbon fluid and is usually transient. The mechanism is believed to be a combination of parenchymal necrosis and check-valve airway obstruction . 4pL影像园XCTMR.com

Radiographs and CT scans.—A pneumatocele appears as an approximately round, thin-walled airspace in the lung (Fig 1). 4pL影像园XCTMR.com
