CASE 765: MESENTERIC ABSCESS due to FISHBONE, Dr PHAN THANH HẢI, Dr LÊ THỐNG NHẤT, Dr VÕ NGUYỄN THÀNH NHÂN, MEDIC MEDICAL CENTER, HCMC, VIETNAM.

A male patient with his right flank pain for 3 days.

Abdominal ultrasound detected a # 12mm fluid-filled appendix with thin wall that was not enough to  diagnosing an acute appendicitis.

Lab data with hs CRP =56.91 represented an infectious syndrome of the abdomen.

To confirm the source of abdominal infection and ruling out an inflamed appendix, an abdomen MSCT was done.

MSCT detected a #14 mm fishbone in an  abscess at the left flank which was wall-off by the mesentery.

Surgery removed the abscess with fishbone succcessfuly which adhesived critically the transverse colon but no clue of coming from the bowel or colon.

MSCT is more sensitive in case of foreign body with high density like fishbone in the abdomen.
