Incidental Findings in Ultrasound

Part of the Medical Radiology book series (MEDRAD)


This chapter describes the most common incidental findings in abdominal ultrasound and gives an overview about their etiologies, imaging features and treatment options. Being aware of unexpected incidental findings in ultrasound and their implications for patient management is a necessity for every sonographer and will assist the physician in clinical decision management. This chapter provides information about abdominal aortic aneurysms, hemangiomas, liver cysts, cholelithiasis, renal cysts and renal cell carcinoma.
