  		Fig. 1B —Splenic laceration with subcapsular hematoma in 46-year-old woman. Longitudinal non-contrast-enhanced sonogram shows central heterogeneous region (arrow) with normal-appearing spleen posteriorly and subcapsular hematoma anteriorly.

  		Fig. 1C —Splenic laceration with subcapsular hematoma in 46-year-old woman. Longitudinal contrast-enhanced sonogram shows that splenic tissue noted posteriorly appears perfused and echogenic. Central region (arrow), which is nonperfused, is more hypoechoic and corresponds to region of splenic laceration. More anterior hypoechoic region corresponding to subcapsular hematoma remains hypoechoic.

  		Fig. 2A —Splenic laceration in 20-year-old woman. CT scan of abdomen shows well-demarcated splenic laceration (arrow).

  		Fig. 2B —Splenic laceration in 20-year-old woman. Non-contrast-enhanced sonogram was interpreted as showing normal findings, whereas this axial contrast-enhanced sonogram shows well-demarcated hypoechoic splenic laceration (arrow), which correlated with appearance on contrast-enhanced CT.

  		Fig. 3A —Splenic laceration in 23-year-old woman. CT scan of abdomen shows regions of normal enhancing splenic tissue (arrow) within splenic laceration.

[in a new window]
  		Fig. 3B —Splenic laceration in 23-year-old woman. Based on longitudinal non-contrast-enhanced sonogram (not shown), spleen was interpreted as normal; however, this axial contrast-enhanced sonogram shows splenic laceration corresponding to region on CT with areas within laceration that were perfused splenic tissue (arrow).

  		Fig. 4A —Liver laceration in 46-year-old woman. CT scan of liver shows fairly well-demarcated region of decreased density within liver (arrow) corresponding to area of injury.

  		Fig. 4B —Liver laceration in 46-year-old woman. Longitudinal non-contrast-enhanced sonogram was interpreted as normal.

 

Figure 10

  		Fig. 4C —Liver laceration in 46-year-old woman. Axial contrast-enhanced sonogram shows central hypoechoic region (straight arrow). Hypoechoic region was surrounded by perfused hyperechoic region (curved arrow).

  		Fig. 5A —Liver laceration in 21-year-old woman. CT scan of liver shows large irregular liver injury.

 

Figure 12

  		Fig. 5B —Liver laceration in 21-year-old woman. Longitudinal non-contrast-enhanced sonogram of liver shows fairly large echogenic region of liver (arrow) that corresponds to site of injury identified on CT.

 

Figure 13
View larger version (140K):

[in a new window]
  		Fig. 5C —Liver laceration in 21-year-old woman. Longitudinal contrast-enhanced sonogram shows echogenic region (arrowhead) to be perfused and to appear slightly more echogenic than normal liver. However, there was nonperfused central hypoechoic region (curved arrow). Also note hematoma in hepatorenal fossa (straight arrow) that was not identified on initial non-contrast-enhanced sonogram.

  		Fig. 6B —Liver laceration in 32-year-old man. Longitudinal non-contrast-enhanced sonogram shows large heterogeneous hyperechoic region (arrow) noted in liver in corresponding area of injury identified on CT.

 

Figure 16
View larger version (128K):

[in a new window]
  		Fig. 6C —Liver laceration in 32-year-old man. Contrast-enhanced sonogram shows that some of peripheral region that appeared hyperechoic on non-contrast-enhanced sonogram is perfused (arrowhead). However, more centrally, there is hypoechoic region (arrow) that corresponds to region of liver laceration, hematoma, or both.

  		Fig. 6D —Liver laceration in 32-year-old man. Contrast-enhanced sonogram obtained in slightly different area shows there is central hypoechoic echoic region (arrow) with surrounding perfused echogenic area (arrowhead).
