ABSTRACT

The majority of fetal chest tumours are benign and tend to be identified in the second trimester. In the absence of fetal hydrops, they usually have a favourable prognosis. The vast majority of chest lesions tend to be unilateral, possibly because bilateral lesions are self-limiting. In many cases they present with mediastinal shift, easily spotted, with the heart axis being deviated to one side (see ‘Dextrocardia’).
