Asymptomatic, Nonmalignant Liver Masses: A Radiologist’s Approach
Asymptomatic liver mass lesions are incidental findings on imaging performed for non-hepatic indications. Advances in radiological imaging and easy availability have led to more frequent use of imaging, resulting in detection of asymptomatic liver lesions. In addition, screening protocols such as CT colonography and cardiac and lung cancer CT screening which include the upper abdomen have resulted in the detection of more incidental liver lesions. These incidental liver lesions have not only created unnecessary concern and apprehension for the patients but also management dilemmas for the clinician. In this chapter, we describe a case of a patient with an incidental liver mass. We briefly discuss the epidemiology and clinical features and focus on the radiologic characteristics of some of the more commonly seen liver benign lesions.
