[Sonography of a mesenteric lymphangioma]

Area of Science:

• Medical imaging
• Gastroenterology
• Surgical pathology

Background:

• Lymphangiomas are benign congenital malformations of the lymphatic system.
• Mesenteric lymphangiomas are rare, typically presenting in pediatric populations.
• Diagnosis often relies on advanced imaging techniques.

Observation:

• A 62-year-old male presented with symptoms indicative of an acute abdomen.
• Initial clinical presentation suggested a surgical emergency.
• Ultrasonography was employed for diagnostic evaluation.

Findings:

• Ultrasonography identified a large mesenteric lymphangioma.
• Evidence of hemorrhage within the cystic spaces of the lymphangioma was observed.
• The hemorrhage was identified as the cause of the acute abdominal symptoms.

Implications:

• This case underscores the potential for mesenteric lymphangiomas to present in older adults.
• Hemorrhage into lymphangiomas can mimic other acute abdominal pathologies.
• Accurate ultrasonic characterization is crucial for timely diagnosis and management of symptomatic lymphangiomas.
