Giant Mesenteric Cyst in a Young Adult Mimicking Refractory Ascites: A Diagnostic and Surgical Challenge-A Case Report.

Mesenteric cysts are rare benign intra-abdominal tumors that are usually asymptomatic and diagnosed incidentally while being investigated for other conditions or their complications. Surgical excision remains the primary treatment option. Here we present the case of a 30-year-old male with progressive abdominal distension, initially misdiagnosed with liver disease and refractory ascites, leading to inappropriate diuretic therapy. Subsequent imaging revealed a giant mesenteric cyst, which was successfully managed with complete surgical excision.
