Ultrasonographic findings of intrahepatic hematoma

Sequential ultrasonography was performed in 22 cases of intrahepatic hematomass diagnosed by operation,laboratory data, the clnical manifestation. We analyzed the shape, location, size of hematoma, and change in sizeand echogenicity by age of hematoma. The results were as follows: 1. The most common shape of intraheppatic hematoma was round. 2. The most common site of intrahepatic hematoma was the posterior segment of the right lobeof the liver, 3. Size of hematoma was decreased from 3rd day, and most hematomas were nearly or completely absorbed from 2nd week to 4th week. 4. Echogenecites of intrahepatic hematoma in immediate ultrasonography after injury showed mainly echogenic or mixed form, and then the echogenecities were decreased and nearly or completely not seen from 2nd week to 4th week.
