Rare case of isolated levocardia with polysplenia including normally structured lung without cardiac anomaly

Abstract

Isolated levocardia (IL) is a rare type of situs inversus in which the heart is in the normal left-side position, but the abdominal viscera are in the dextroposition. Polysplenia is a congenital disorder affecting the asymmetric organs, including the heart, lungs, bronchi, liver, stomach, intestines, and spleen. In this report, we present a rare type satisfying the characteristics of both IL and polysplenia, confirmed by several imaging investigations, which revealed normally structured lungs and heart and the existence of the inferior vena cava (IVC), which runs on the left side, returns to the anterior-right side at the liver, and returns to the right atrium directly. Anatomical investigation and careful observation will make it possible to improve the prognosis of IL.
