Sparganosis is a rare parasitic infection caused by larvae of the genus Spirometra. It can involve any part of the human body and usually manifests as a mass in various locations. We report a case of recurrent sparganosis in the breast and lower extremities. Our patient had recurrent subcutaneous masses in her breast and lower leg that showed characteristic ultrasonographic imaging findings of serpentine, tubular structures with surrounding increased echogenicity. These imaging findings are well correlated with pathologic findings. Worms were identified in resected specimens confirming sparganosis.
