Mesenteric cysts.

Introduction: Mesenteric cysts are benign tumours frequently found during surgical procedures due to different causes. The primary tumours of omentum can be found as solid or cystic masses. They usually originate from mesenteric lymphatics which produce closed spaces with fluid within. The size of these cysts can be enormous. They can be attached to the gastro-intestinal tract, or originate in solid organs.

This paper presents the cases we handled at hospital during the last 3 years.

Aims: To illustrate the characteristics of mesenteric cysts treated at our hospital.

Results: Non-parasitic, peritoneal cysts are regarded as the most frequent type of mesenteric cysts nowadays. Tumours developed from mesenteric root are quite rare, according the literature reviewed. This paper presents our findings of an omental cyst, the blood supply of which emerged from the upper mesenteric artery. The cyst was attached to duodenum, small bowel and large bowel.

Conclusions: Mesenteric cysts are uncommon conditions due to embryological defects. Acquired, non-parasitic omental cysts, however, present more often in this region compared with ones caused by abnormal development of mesentery. Local statistics and demographics relating to this condition are presented, as well as ultrasound and computed tomography images, morphology and surgical procedure in one case.
