Figure 27a. Biloma and pseudoaneurysm. (a) Initial contrast-enhanced CT scan shows multiple lacerations and a hematoma in the right hepatic lobe and the medial segment of the left hepatic lobe. (b) Follow-up contrast-enhanced CT scan obtained 26 days later shows development of a biloma (arrow) and a pseudoaneurysm (arrowhead). The patient underwent transarterial embolization and percutaneous catheter drainage. Clear noninfected bile was drained.
