Whether shallow lobes are serious or not in CT film of lungs needs further examination, and it is impossible to judge by this result alone, and its common causes include congenital lung malformation, lung inflammation or tumor. 1. Congenital lung malformation: abnormal development of the lungs leads to congenital lobar malformation, which can be manifested as nodules in the lungs with shallow lobes around the edges, and the shallow lobes in this case are not serious. 2. Inflammation of the lungs: Inflammatory reaction of the mucosa of the lungs caused by pathogen infection, resulting in inflammatory nodules with shallow lobular edges, which can be treated with targeted anti-pathogen drugs. 3. Tumor: damage to the lungs, lung tissue damage, tumor cells invade the lung tissue, appearing lung nodules, the edge of the shallow lobed, this situation is more serious, should be carried out as soon as possible anti-tumor treatment. There may be other reasons for the shallow lobulation in lung CT film, it is recommended to improve the examination in time to clarify the reasons and carry out standardized treatment under the guidance of doctors.
