Incidental renal mass found on focused assessment with sonography in trauma.

We present the case of a 9-year-old female who presented after minor blunt abdominal trauma during a sporting event. On focused assessment with sonography for trauma, she was found to have an incidental renal mass, which was ultimately diagnosed as a renal cell carcinoma. In this report, we focus on the use of bedside ultrasound as a screening test and the management of incidental findings.
