A Rare Case of a Large Intra-Abdominal Lymphatic-Venous Malformation in a Young Girl Who Access to the Emergency Room for Abdominal Pain

Résumé fourni par la source

Lymphatic-venous malformations (LVMs) are rare congenital low-flow vascular anomalies characterized by abnormal, interconnected lymphatic and venous vessels. These malformations can occur anywhere in the body, but they are most commonly found in areas rich in lymphatic tissue, such as the head and neck, axilla, mediastinum, and groin1. Fewer than 5% of LVMs are located intra-abdominally, typically arising from the mesentery, retroperitoneum, or greater omentum. Patients with intra-abdominal LVMs may be asymptomatic, but they can also pre-sent with symptoms such as acute abdominal pain, chronic discomfort, palpable masses, or progressive abdominal distension. The diagnosis of LVMs can be challenging and requires a combination of imaging techniques, including ultrasound (US), computed tomography (CT), and magnetic resonance imaging (MRI), along with histological con-firmation. This case describes a 24-year-old female who presented to our Emergency Depart-ment with progressive abdominal distension, nausea, and vomiting.
