In this chapter non-traumatic and traumatic pathology of the spleen will be discussed. A variety of non-traumatic emergencies of the spleen are regularly encountered during emergency imaging of the abdomen. Sometimes diagnostic imaging is performed because the splenic pathology (infarcts, spontaneous rupture, abscess or splenomegaly) causes symptoms, more often these splenic abnormalities are encountered during diagnostic imaging for other indications. We will discuss the most common splenic findings that can be encountered during emergency imaging of the abdomen. The spleen is the most affected organ in patients with abdominal organ injury after blunt trauma. Imaging finding of traumatic injury to the spleen on Ultrasound and CT will be described and shown. The influence of imaging in selecting patients for non-operative management of splenic injuries and the value of the most frequently used grading systems in clinical decision making will be discussed.
