Acute abdomen caused by a giant lymphangioma cavernous of the small bowel mesentery, mimicking a mass at the vaginal cuff

Lymphangioma is an unusual lymphatic system malformation that rarely affects adults' mesentery. Even though it is a benign tumor, its capacity to grow and affect nearby structures can cause severe morbidity and even mortality in specific patients. As symptoms are nonspecific, a highlighted clinical insight is needed to reach a diagnosis. We present a case of a 60-year-old woman who presented with abdominal pain and suffered acute abdomen due to a lymphangioma in the mesentery of the small bowel; after complete resection, the patient achieved full recovery.
