Case Report: Spontaneous Resolution of Intracavitary Hepatic Artery Pseudoaneurysm Caused by Amebic Liver Abscess following Percutaneous Drainage.

Intrahepatic pseudoaneurysm (IHPA) is generally iatrogenic, and it warrants urgent management because of its reportedly significant risk of rupture leading to considerable mortality. Intrahepatic pseudoaneurysm caused by amebic liver abscess (ALA) is exceedingly rare with fewer than seven published reports. All reported symptomatic cases have been treated with hepatic artery embolization; therefore, little is known about its natural course and effect of abscess drainage on its outcome. We report the first case of symptomatic intracavitary IHPA caused by ALA in which ultrasound-guided percutaneous catheter drainage of the abscess resulted in the spontaneous resolution of the IHPA.
