Her blood pressure was 139/88 mm Hg in the right upper extremity and 133/80 mm Hg in the left upper extremity. Her heart rate was regular, and breath sounds were clear. She had mild abdominal tenderness in the umbilical and left lumbar regions.

Electrocardiography and laboratory testing, including troponins, showed no abnormalities. Computed tomography of the chest and abdomen with contrast enhancement showed no evidence of aortic dissection or pulmonary embolism. However, postcontrast images detected nonobstructing calculi in the left kidney and air emboli in the peripheral venous circulation (Figure 1), right ventricle (Figure 2), and pulmonary trunk (Figure 3). The air emboli were thought to be most likely from peripheral intravenous catheter placement or manipulation for contrast injection.
