Sonographic Bands of Hypoechogenicity in the Spleen in Children: Zebra Spleen.

摘要: OBJECTIVE. Zebra spleen is the normal pattern of splenic enhancement during arterial phase CT and MRI attributed to different flow rates. The purpose this study was describe appearance occurrence bands hypoechogenicity in on unenhanced sonograms children with no abnormalities. MATERIALS AND METHODS. We reviewed 100 abdominal ultrasound studies evaluate characteristics spleen. Demographic data were collected for all patients. RESULTS. Homogeneous echogenicity found 92 children. Heterogeneous present eight. Three eight had discrete macronodules due known disease. other five hypoechogenicity. These disease, but one mild splenomegaly unknown cause. CONCLUSION. hypoechoic occurred 5% our series. This cannot be explained simply by rates probably reflects structu...
