摘要: A new sonographic pattern of pulmonary consolidation associated with air-filled bronchi in children is presented. The consolidated area the lung usually hypoechoic, poorly defined, and wedge-shaped. produce linear, high-amplitude branching echoes that converge toward root. Posterior acoustic shadowing reverberation artifacts are seen accompanying proximal large bronchi. comparative study presented which 30 pediatric patients clinical radiographic evidence pneumonia were sonographically evaluated. Twenty-eight successfully examined sonography. cases divided into three groups: (1) without pleural effusion (19 patients); (2) small (five (3) partial compression atelectasis due to (four patients).
