Sparganosis mansoni in adipose capsule of the living related donor in one case / 中国组织工程研究

ABSTRACT

Parasitism characteristics of spirometra mansoni sparganum in the living donor kidney are analyzed by present cases and relevant literatures. A female aged 49 years voluntarily donated a kidney to her son. Results of healthy evaluation were accorded with the standards of living donor kidney. During repairing kidney, a sliver cyst was found in the adipose capsule on the kidney ventral surface, near to the renal hilum. The cyst was incised, and a ivory white girdle-shaped worm was obtained. After identification, the worm was identified spirometra mansoni sparganum (living body). Pathological examination showed that the cyst developed granulomatous inflammation, combined with neutrophil and eosinophilic granuiocyte infitration. Following surgery, the donor and recipient were treated with praziquantel. No proglottid or worm ovum was detected by dung detection within 3 months, without any discomfortable symptom. The infection mode and pathway may be by eating unmatured paratenic host meat or infected cyclops. The donor and recipient should be examined for parasitic infection of sparganosis mansoni prior to transplantation. No significant symptom could be detected following parasitism of sparganosis mansoni in the kidney, so it was seldom found. Worm ovum was examined in feces, which could be the evidence for sparganosis mansoni and for case history inquisition. Eosinophilia in the blood always indicated that chronic parasitic infection. Zoogenetic infection test could be tested when necessary. Sparganum antigen could be used for various immunological tests, which could provide evidence for auxiliary diagnosis of immunology. The diagnosis was usually confirmed by obtaining a polypide by surgery or histological examination. CT scanning and magnetic resonance imaging have diagnostic value of renal sparganosis mansoni.
