Renal Cysts: An Issue of Concern

Abstract

Simple renal cysts are frequent benign conditions that rarely evolve to malignancy. Complications include rupture, hemorrhage, infection, and local compression effects. Benign cysts are most often asymptomatic and incidentally detected by imaging tests, which reveal that these changes can increase in size doubling their volume in a decade. The Bosniak classification is widely utilized as a useful guide for diagnosis and control, and the uncomplicated cysts usually do not need invasive procedures or interventions. An elderly female with asymptomatic simple cysts in the left kidney and antecedent of partial mastectomy and total thyroidectomy due to malignant tumors is here reported. The registered comparative abdominal images of a long-standing control are shown.
