CASE 656: BOWEL VOLVULUS due to MESENTERIC CYST, Dr PHAN THANH HẢI, Dr TRẦN NGÂN CHÂU, MEDIC MEDICAL CENTER, HCMC, VIETNAM

 

A 23 year-old male patient with periumbilical pain and left flank pain for 5 days and vomiting. 

Ultrasound detects a cystic mass # 17.9x11.2 centimeter from his navel to pubis, and jejunum dilatation with obstruction sign (washing machine sign). The cystic mass contents fluid and septation with vascular sign on its walls. The cause of bowel obstruction was noted by a non-dilated bowel loop at the mesenteric root with whirpool sign.

There is not  bowel malrotation nor duplication cyst, so the ultrasound findings is bowel volvulus due to a mesenteric cyst.

MSCT confirms bowel volvulus due to a mesenteric cyst later.

Open surgery is done after endoscopic investigation. The cystic mass with yellowish fluid and a part of bowel are removed. Patient remains well post-op.

The histopathological report is a benign cyst with inflammation of the mesentery.

 

Bowel volvulus is still a rare entity especially in young adult.  Mesenteric cyst causes bowel volvulus may happen in emergency room in case of ruling out bowel malrotation, urachal cyst, Meckel diverticulum.
