Chest radiograph in a patient with situs inversus and atrial isomerism

Anterior-posterior view of a chest radiograph of a patient with situs inversus and atrial isomerism: The apex of the heart is rightward, consistent with dextrocardia. The obtuse angle right mainstem bronchus (RMSB) and liver are leftward, while the stomach bubble and acute angle left mainstem bronchus (LMSB) are rightward, all consistent with situs inversus. Note that the left diaphragm is slightly higher due to the presence of the left-sided liver, while the trachea is shifted leftward due to the presence of a right aortic arch, which is to the right of the trachea and arches over the LMSB.
