The incidence of pyogenic liver abscesses (PLAs) resulting from foreign body ingestion is relatively rare; however, it poses significant risks, necessitating timely diagnosis and intervention. This report presents an unusual case involving a 77-year-old female who developed a PLA following the ingestion of a fishbone. The patient was accurately diagnosed using high-resolution computed tomography-based three-dimensional reconstruction and subsequently underwent successful treatment through laparoscopic incision, drainage, and simultaneous removal of the fishbone.
