BRIGHT BAND SIGN in SPLENIC INFARCTION

In summary, the bright band sign was apparent in 91.9% of patients with splenic infarcts, including 95.7%
of those with nonclassic sonographic features of splenic infarction, was not present in a collection of 19 abnormal control patients, and was not seen in 100 normal control patients.
The bright band sign likely results from specular reflections returned from fibrous trabeculae that remain intact within infarcted regions while the neighboring splenic parenchyma undergoes necrosis. Although further work will be required to establish the role that the bright band sign may play inthe diagnosis of splenic infarction, the sign appears potentially useful, particularly for the many infarcts with nonclassic, nonspecific sonographic appearances.
