Fig. 10From: Non-contrast 3D MR lymphography of retroperitoneal lymphatic aneurysmal dilatation: a continuous spectrum of change from normal variants to cystic lymphangiomaA 25-year-old man presenting with non-specific abdominal discomfort. Two communicating cystic lesions are demonstrated. The upper lesion is a round bulky cystic lesion with mass effect on the small bowel on T2-weighted MR image (a). MR lymphography with coronal MIP image (b) demonstrates communication of the upper portion with retroperitoneal lymphatic system (arrowhead). The lower position communicates (arrow) with the lower lesion which is infiltrative and multiloculated. Communication between the two locations is also well demonstrated on MIP sagittal reconstruction (c). Lymphatic nature of the upper lesion and communication with the lower lesion was proved at surgeryBack to article page
