Retroperitoneal tumors can be malignant or benign and they are classified according to the tissue where they are originated. Among them, kidney tumors are those that are becoming increasingly representative, particularly renal clear cell carcinoma, in their different forms of clinical presentation, including a large group of asymptomatic patients. The case of a female patient with left lumbo-abdominal pain is presented, associated with recurrent urinary tract infections, several months of evolution. By ultrasound, one predominantly cystic complex picture was found in the upper pole of the left kidney with solid elements inside and thin walls, which did not rule out the possibility of a variety cystic carcinoma; after being subjected to surgical treatment, tumor histology showed that it was schwannoma of renal cavities, benign type. The evolution of this patient was successful.
