A RARE CASE REPORT ON AN INCIDENTAL MASSIVE RETROPERITONEAL ASCENDING COLON MESENTERIC CYST

Background: The discovery of cystic lesions within the retroperitoneal region is a rare occurrence that presents clinicians with the problem of a difcult diagnosis and management of the condition. The present paper details the management of a case wherein a substantial cystic lesion was incidentally identied following an episode of dengue fever during a routine abdominal scan. Case Presentation: A 24-year-old male presented to the surgical outpatient department (OPD) with the incidental discovery of an intra-abdominal cystic mass during an ultrasound scan conducted as part of his evaluation for dengue infection. He underwent surgery and was discharged after a successful recovery. Conclusion: Mesenteric cysts are uncommon benign abdominal lesions with a 3% risk of malignant development. Most cysts are asymptomatic and are discovered by chance or during the treatment of their problems. The mesentery of the small bowel is the most common origin, followed by the mesocolon. A case report of a 24-year-old male with a huge abdominal mesenteric retroperitoneal cyst arising from caecum and ascending colon is presented
