Multilocular cyst of the kidney in a child. Usefulness of MRI

We report one case of multilocular cyst of the kidney in one year and three months female infant who underwent echography, computed tomography and MRI before surgery. MR image accurately reflect the morphology of the tumor: the capsule is hypointense on T1-weighted images, the septa show moderate enhancement with intraveinous contrast. Varied intensities from fluid in the visualized locules presumably represent different concentration of proteins. MR imaging features are highly suggestive but non pathognomonic of the disease. Positive diagnosis always require histology. (authors). 7 refs., 7 figs
