case_images: Magnetic resonance cholangiopancreaticography showing obstructive biliary processes associated with stent dysfunction of the extrahepatic and common bile duct. Intraluminal irregular images (yellow arrow) of low signal intensity on T2-weighted sequences consistent with bile stones are observed; these lead to moderate dilation of the intrahepatic bile duct.

case_images: To evaluate a probable biliary obstructive syndrome, an abdominal ultrasound and a magnetic resonance cholangiopancreatography were performed (Figure 1), which showed obstruction of the bile duct, secondary expansion, and presence of multiple gallstones.
case_images: Contrast enhanced coronal and axial chest CT. Subsegmental artery air embolism in apical segment of right lower lobe surrounded by contrast media is observed (yellow arrows).

case_images: A CT angiography was done to rule out massive thromboembolism, which evidenced air embolus in the subsegmental arteries of the apical segment of the right lower lobe (Figures 2 and 3) and gas within the IVC in its hepatic portion (Figure 4).
case_images: Contrast enhanced sagittal chest CT. Intravascular filling defect with air density bubble in subsegmental artery (yellow arrow) of apical segment of right lower lobe, bronchus is underneath.

case_images: A CT angiography was done to rule out massive thromboembolism, which evidenced air embolus in the subsegmental arteries of the apical segment of the right lower lobe (Figures 2 and 3) and gas within the IVC in its hepatic portion (Figure 4).
case_images: Contrast enhanced axial CT view showing air embolism (black arrow) inside intrahepatic portion of vena cava.
