Presentation
Renal colic
Patient Data
The right kidney is decreased in size with a subcapsular fluid collection compressing the renal parenchyma. The left kidney is normal in size with a small subcapsular fluid collection mainly at the posterior aspect of the upper pole (well-visualized on the coronal reconstruction) as well as the presence of small cortical renal cysts.
No hydronephrosis or calculi of the urinary tract.
Both renal veins are patent.
Case Discussion
CT features suggestive of bilateral renal lymphangiectasia (predominately on the right). It is considered as a rare benign condition, characterized by dilated cortical endothelial-lined spaces with no glomerular or tubular abnormalities.
