Synonyms
- Mesenteric or omental cyst; lymphangioma (antiquated)
Definitions
- Subtype of congenital slow flow vascular malformation due to error of lymphatic vessel formation
- Results in well-defined cyst-like (macrocystic) &/or infiltrative, solid-appearing (microcystic) mass of abnormal lymphatic channels focally or diffusely within mesentery
- Individual cyst size: Macrocyst > 1 cm, microcyst < 1 cm
- Mass lacks communication with normal lymphatics
- Not neoplastic
