FIGURE 7.

Mesenteric lymphangioma. Transverse grey scale ultrasound images (a, b) of the abdomen in a 3-year-old male child reveal an ill-defined multiloculated irregular-shaped thin-walled cystic lesion in the mesentery showing posterior acoustic enhancement. The lesion is located anterior to bilateral kidneys, pancreas (white arrow) and aorta. Multiple thin septations are noticed within the lesion creating a ‘cobweb’ appearance. Echogenic contents are seen within few loculi resulting in differential echogenicity of loculi. No calcification is noticed within the lesion. Axial contrast enhanced CT images (c, d) in the same patient reveal a multilobulated thin-walled fluid density cystic lesion in the mesentery anterior to pancreas and aorta. The lesion is insinuating between leaves of mesentery and bowel loops. Mesenteric vessels can be seen traversing through the lesion.
