Hepatic artery pseudo-aneurysm and hepato-fastric fistula are extremely rare clinical entities, which can be caused as complications of amoebic liver abscess. Herein, we report a 45- year old man, who presented with history of hematemesis since last 1 day, melena since last 3 days and fever since last 5 days. On physical examination, he was hemodynamically stable, pallor was noted. Abdominal examination revealed tenderness over the right-upper quadrant. Per-rectal examination showed evidences of melena. Esophagogastroduodenoscopy revealed stomach communicating anteriorly with the abscess cavity from the surrounding, possibly from liver. There was no evidence of fresh bleed during the procedure. The abscess was drained and sent for microbiological evaluation. Computed tomographic angiography revealed a well defined saccular outpouching arising from common hepatic artery with surrounding ill-defined hypodensity around segment V and IVb of liver. Patient underwent transfemoral endovascular coil embolization. Post embolisation, DSA showed complete occlusion of pseudo-aneurysm. He was discharged on oral metronidazole and was doing well on 8-month follow-up with no episodes of rebleed.
