[Bilateral renal lymphangiomatosis: conservative management]

Lymphangiomatosis is a benign disease of difficult diagnosis. The bilateral form is very rare, being in some cases an incidental finding.

We report the case of a female patient with the incidental radiological diagnosis of bilateral lymphangiomatosis, who did not present symptoms in relation to the disease.

After a meticulous study with ultrasound, abdominal CT scan and the MRI the diagnosis was asymptomatic bilateral lymphangiomatosis and expectant management was decided with good outcome.

Most cases reported have been treated by nephrectomy for diagnosis, but in our case it was possible to do precise diagnosis adding the experience of the radiologist and the urologist and she had a good outcome with conservative management.
