Imaging Findings of Splenic Paragonimiasis: Using Contrast-Enhanced Ultrasonography

摘要

Splenic paragonimiasis is a very rare form of ectopic infestation caused by Paragonimus. We report a case of paragonimiasis presenting as splenic mass. Dynamic contrast-enhanced sonography revealed a hypoechoic mass consisting of multiple clustered cysts with persistently minimal enhancement of the wall in the spleen. This finding appears to be characteristic for splenic paragonimiasis and ectopic paragonimiasis should be included in the differential diagnosis of splenic mass.
