Abstract
Cystic hemolymphangioma and jejunal duplication are both typically congenital conditions and primarily identified in childhood, making adult diagnoses exceedingly uncommon. Cystic hemolymphangioma and intestinal duplication together are particularly rare. In this report, we present the case of an adult female patient with both. A pedunculated mass was identified outside the jejunal wall, with duplicated intestine on the stalk and cystic hemolymphangioma within the mass. Both lesions were surgically excised, and the patient has remained recurrence-free for five years postoperatively.
