case_images: Preoperative imaging examinations of the patient. (A) An accidental chest x-ray showing a striped high-density shadow in the hepatic region. (B-D) Contrast-enhanced CT showing the major part of the sewing needle trapped in the liver parenchyma with the tip closest to the sagittal part of the left branch of the portal vein. (E,F) Ultrasound images showing a minimal distance between the sewing needle and portal vein.

case_images: The shadow with a line hole at the end of one side suggested the presence of a sewing needle (Figure 1A). Unexpectedly, the sewing needle seemed to have entirely entered the liver with the tip adjacent to the sagittal part of the left branch of the portal vein (Figures 1B-F).
case_images: Intraoperative findings. (A) The line hole of the sewing needle exposed the surface of the liver and was partially covered by hepatic capsule. (B,C) The sewing needle broke into pieces after clamping and pulling. (D) The lower and middle parts of the sewing needle were rusty; and the length was 3.7 cm.

case_images: Intraoperative findings revealed that the enlarged part of the line hole was only exposed slightly above the surface of the liver (Figure 2A). At first, we tried to remove the sewing needle by clamping and pulling (Figure 2B). As a result, the sewing needle broke into parts in the process of removal (Figure 2C). Rust had covered the lower and middle parts of the sewing needle (Figure 2D).
