Fig. 7

An 18-year-old man presenting with abdominal discomfort. CT scan (a) demonstrates a large infiltrative retroperitoneal cystic lesion. On T2-weighted MR image (b) it appears multiloculated, with thin wall and septa. The content is serous with flow phenomena, appearing as characteristically shaped signal heterogeneity on T2-weighted images. Sagittal T2-weighted MR image (c) and coronal MIP image (d) show extensions (arrow) adjacent to surrounding lymphatic channels
