Abstract:
Pulmonary cavitary lesions in children consist of a group of heterogeneous diseases, mainly caused by infections, and their imaging manifestations can be similar.It is clinically difficult to distinguish them from other lesions such as bullae, cyst, and emphysema.Some scholars have advanced a concept about thin wall(4 mm or less) and thick wall(more than 4mm).People tried to make this distinction by defining cyst as a thin wall and cavity as a thick wall, but there are considerable overlaps between the two categories in etiology and pathophysiology.They are sometimes difficult to distinguish for imageology, and it is still necessary to find the cause of the disease based on the characteristics.This review divides etiology into two categories: infectious and non-infectious etiology.Combined with chest imaging examination, the purpose is to analyze and summarize the features of pulmonary cavitary lesions in children, and provide a diagnostic idea for differentiating various pulmonary cavities to guide clinical treatment.
