Large mesenteric cyst from the small bowel mesentery in a young pregnant female with calcular cholecystitis

Rationale: Mesenteric cysts are rare abdominal tumours that can originate from any part of the mesentery of the bowel but have been found mostly in the mesentery of the small bowel. Patient Concerns: Because they lack specific clinical signs, mesenteric cysts can be difficult to diagnose. Diagnosis: Especially when there are concomitant abdominal conditions. In some circumstances, these cysts can grow to considerable sizes making resection almost impossible as different structures can be compromised. Intervention: Surgery is the treatment of choice as complete resection is the only curative treatment. Outcome: We present the case of a 27-year-old pregnant female patient who presented with recurrent abdominal pain and was discovered to have calcular cholecystitis along with a huge mesenteric cyst. She underwent laparoscopic cholecystectomy with complete excision of the mesenteric cyst without the need for bowel resection and anastomosis.
