case_images: Sparganosis. Ultrasonography shows a serpiginous hypoechoic structure and this compartment is surrounded by a hyperechoic area

case_images: On ultrasonography, a hypoechogenic structure, measuring 2.0cmx2.0cm in size adjacent to a hyperechogenic area was observed (Fig. 1).

case_images: A long, slender, whitish, non-vermigrade worm, approximately 10 cm in length and 5 mm in width was removed (Fig. 2).
case_images: Cross section of sparganum. Many calcareous corpuscles were observed in the cavity (arrows) (H&E x 100)

case_images: The parenchyma was composed of parechymal cells, calcareous corpuscles, excretory ducts and muscle fibers (Fig. 3).
case_images: The plerocercoid was surrounded by fibrous tissue and mixed inflammatory cell infiltrates, including lymphocytes and eosinophils. (H&E, x100 and x400 [inset])

case_images: (a) The results of a multiple-dot enzyme-linked immunosorbent assay (ELISA) for the diagnosis of parasitic disease. (b) Anti-sparganum mansoni IgG antibody titers measured by microplate ELISA. Antibody titers are expressed as the optical density (O.D.) at 405 nm. A value of 0.1 or less was considered nonspecific

case_images: Because her serum was positive for S. mansoni in this assay (Fig. 5a), we tested for parasite-specific IgG antibody using a microplate ELISA for further investigation. The result clearly showed that her parasite-specific IgG antibody titer was high (Fig. 5b). The serum titer of the parasite-specific IgG antibody had decreased significantly (Fig. 5b).
