A rare case of giant mesenteric lipoblastoma causing an abdominal mass in an 8-month-old child.

Introduction And Importance: Giant mesenteric lipoblastoma (LB) is a rare and benign tumor derived from adipocytes. It may imitate malignant tumors, and its diagnosis is challenging before surgery. The diagnosis can be guided by imaging studies but cannot be confirmed. Just a few cases of lipoblastoma originating from the mesentery are reported in the literature.

Case Presentation: We present a case of a rare giant lipoblastoma arising from the mesentery of an 8-month-old boy who consulted our emergency department for an incidentally discovered abdominal mass.

Clinical Discussion: LB is most common in the first decade of life, with a high incidence in boys. LBs are generally found in the trunk and extremities. Intra-abdominal locations are rare; however, intraperitoneal tumors generally reach larger dimensions.

Conclusions: Tumors that arise in the abdomen are usually larger and may be discovered by physical exam as an abdominal mass and may cause compression symptoms.
