A hemangiolymphangioma of the small intestinal mesentery encircled superior mesenteric vessels: case report and review.

Introduction and importance: Hemangiolymphangioma of mesenteric origin are extremely rare. Here, we reported a case of giant hemangiolymphangioma of the small intestinal mesentery which encircled superior mesenteric vessels. Case presentation: We reported a case of a patient with hemangiolymphangioma who underwent surgical treatment, with the diagnosis confirmed through histological examination. Clinical discussion: The preoperative diagnosis of mesenteric hemangiolymphangioma is reasonably difficult. Despite advanced imaging techniques, mesenteric hemangiolymphangiomas are often misdiagnosed. Although imaging technologies can identify an abdominal mass, they cannot provide a definitive diagnosis, which requires histopathological confirmation. Surgical resection remains the primary treatment for hemangiolymphangioma based on existing literature. Conclusion: The mesenteric hemangiolymphangioma is extremely infrequent. A definitive diagnosis is often challenging to establish preoperatively and is usually confirmed through histopathological examination of the resected specimen.
