Presentation A young woman presented for ultrasound of the thorax for an opacity seen on chest radiograph. She was completely asymptomatic as far as chest symptoms were concerned. The chest radiograph was taken as a routine for pre-anaesthetic check up.
 
 
 
Caption: Radiograph of the chest
Description: Near complete opacification of the left hemithorax is noted. The opacity silhouettes the ipsilateral diaphragm and the cardiac border. No significant shift of mediastinal structures is noted.
 
 
 
Caption: Oblique scan of the left thoracic region
Description: A well- defined, predominantly cystic mass is seen within the echogenic lung mass. A highly echogenic nodule is seen within that mass.
 
 
 
Caption: Transverse image of the left lung mass
Description: The characteristics of the left lung mass are seen again in this image. The cyst wall appears to be thick.
 
 
 
Caption: Coronal reconstructed CT scan
