Nontraumatic hepatic artery pseudoaneurysm associated with acute leukemia: a possible complication of pyogenic liver abscess

We present a case of hepatic artery pseudoaneurysm resulting from a pyogenic liver abscess, which has not been described previously, in a patient with acute leukemia receiving chemotherapy.
