Abstract

　　Chest radiography is the most frequently performed procedure and is the initial examination for pediatric lung disease. The diagnosis of pneumonia is one of the most important challenges facing a radiologist interpreting a child’s chest radiograph. The thymus is extremely variable in its radiographic appearance and sometimes shows findings mimicking those of pneumonia, cardiomegaly or mediastinal tumor. It is important to know the normal thymus various to interpret the chest radiograph. In this paper, there are two themes, “thymus” and “pneumonia”. I focus here on the radiological appearance of the typical and atypical features of thymic tissue and pneumonia.
