INTRODUCTION: @entity361 are an exceptional finding in the urinary tract and @entity8 is even more rare. They are usually discovered incidentally during ultrasonography examinations or autopsy. Sometimes they are clinically symptomatic with @entity811 , @entity812 , or palpable mass. Till today, it is still difficult to make a diagnosis of @entity2909 using the radiological examinations. Although conventional imaging has a high sensitivity and specificity in the detection of both retroperitoneal and renal masses, the diagnosis is based on histological examination, due to the poor discrimination accuracy between @entity5 . CASE DESCRIPTION: We report a case of @entity8 in a 47-year-old @entity1 , who incidentally discovered a retroperitoneal mass with an abdominal ultrasound scheduled for a conventional follow-up schedule of a mammary @entity5 . Partial nephrectomy was carried out with an open flank surgical approach and the diagnosis was " @entity2909 of the renal capsule". Four years after surgery, the @entity1 is disease-free. CONCLUSIONS: @entity8 are rare, benign, nonmetastasizing @entity5 with a good prognosis after surgical treatment. At present, the differential diagnosis is still possible by histopathological examination.
