A 3.5-year-old girl with a right pleural effusion and a lung infiltrate.
A tube was inserted into the right hemithorax.
(a)Chest CT (lung window):
a right hydropneumothorax is present. Part of the tube is seen anteriorly;
its tip cannot be accurately defined.
(b) Chest CT (mediastinal window, same level as (a)):
again the tip of the tube is not well visualized owing to artefacts from ametallic device on the left chest wall, but it probably
abuts the superior vena cava and the ascending aorta.
