Diagnostic Ultrasound - Abdomen and Pelvis
Splenic Infarct (Left) Power Doppler US of the spleen in longitudinal plane shows a central, welldemarcated, wedge-shaped area of relative hypoechogenicity . There is diminished (but not absent) power Doppler signal within the area of infarct ſt. (Right) Corresponding coronal CECT in a patient with end-stage liver disease with portal hypertension marked by massive ascites and splenomegaly with central infarct . Streak artifact from metallic embolization coils present ſt (therapeutic splenic artery emobilization). Diagnoses: Spleen (Left) Rounded polar splenic infarct is shown on grayscale US. The infarcted area is hypoechoic and welldemarcated . Color Doppler (not shown) demonstrated absent flow. (Right) A mimic of splenic infarction is splenic laceration, shown here as a well-defined, hypoechoic, band-like area extending to the subcapsular region. The history of trauma is an important differentiating factor. The spleen is the most frequently injured intraperitoneal organ in patients with blunt abdominal trauma. (Left) Axial NECT shows a heavily calcified and heterogeneous spleen ſt, indicating chronic, and possibly acute, infarction. (Right) The splenectomy specimen shows a mottled spleen with capsular discoloration st that was heavily calcified on microscopy. 417
