MRI as Non-Invasive Modality of Choice for Diagnosis of Cause in Case of Chyluria

Chyluria is a urological manifestation of lymphatic system abnormality as a result of some abnormal communication between these two systems. Although chyluria as such is rare, filariasis is most common cause in Asian countries. This parasitic tropical debilitating disease is known for chronicity, recurrence and resultant complications. This article provides importance of Magnetic Resonance Imaging (MRI), as a non-invasive modality, in the diagnosis of exact etiopathogenesis of chyluria along with clinical symptoms, other investigations required and brief about the management protocols. On MRI, abnormally dilated lymphatics are visualized as meshwork of multiple tubular, tortuous, fluid-filled structures in the retroperitoneum. We report a case of 20 year young adult who presented with history of passing whitish urine on and off since 8 months. MRI helped in the detection of the site and level of lymphatic obstruction and resultant lympho-urinary fistula.
