Situs inversus totalis.

We present a case of situs inversus totalis. A 22-month-old infant presented with cyanosis, double-inlet left ventricle, severe pulmonary stenosis, and concern for underlying visceroatrial abnormalities. Chest (Fig. 1) and abdominal (Fig. 2) radiographs were obtained. Abdominal sonography was performed to clarify the presence of splenic tissue and further define the relationships of the inferior vena cava and abdominal aorta (Figs. 3-7). This case demonstrates typical radiographic and sonographic findings of situs inversus totalis and shows the utility of sonography.
