title: Retroperitoneal paragonimiasis: a case of ectopic paragonimiasis presenting as periureteral masses.
abstract: We describe a case of retroperitoneal paragonimiasis presenting as periureteral masses. CT showed a conglomerate of enhancing nodules with subtle low attenuation in the center at the left iliac fossa and clustered, ring-like, enhancing lesions at the left renal hilum. When a retroperitoneal conglomerate of ring-like, enhancing lesions in association with pleuropulmonary disease suggestive of paragonimiasis can be found in endemic regions or in migrants from those regions, one may expect ectopic-retroperitoneal paragonimiasis.
