Figure 2 Intra-arterial contrast-enhanced ultrasound (IA-CEUS) diagnosis of intrahepatic biloma. A 50-year-old man developed hepatic artery thrombosis after hepatic artery balloon dilation, due to low hepatic artery flow 2 months after liver transplantation. (A) Two-dimensional ultrasound detected hypoechoic area in the liver. (B) Portal vein showed good perfusion, while the adjacent hepatic artery showed no perfusion on IA-CEUS. (C) IA-CEUS showed non-enhanced area in the liver, indicating a biloma. (D) The patient underwent emergency surgical resection of the lesion. (E) Postoperative pathology confirmed the biloma ().
