[Natural history of cancer of the kidney: iconographic follow-up].

OBJECTIVE
To describe the natural history of renal cancer based on the images obtained in a case with more than 11 years' follow-up, from the initial stages of the disease to its outcome.


METHODS/RESULTS
The history of a female patient in whom a renal mass had been detected at age 25 years is described. The patient died 11 years later due to metastasis. The images obtained throughout follow-up clearly illustrate the natural course of the disease, which could not be changed because the patient had refused surgery.


CONCLUSIONS
The observation of a small renal mass in young patients is an indication for early surgery. The natural course of this disease is predictably fatal, its benign behaviour being highly questionable. Because pregnancy does not appear to accelerate the course of the disease, patient assessment can be completed and treatment can be instituted after delivery.
