Alveolar cell carcinoma, also known as bronchiolar-alveolar cell carcinoma, is a rare type of primary lung cancer. Occurs in the distal lung bronchioles or alveoli, with a high degree of differentiation, growing along the alveolar wall, and more do not destroy the original alveolar structure. Its X-ray performance is varied. Early identification and qualitative diagnosis are more difficult and easy to misdiagnose. In order to raise awareness of their X-ray signs, we have collected the disease in our hospital for the past 5 years.
