Encased by Infection: A Rare Case of Retroperitoneal Fibrosis Induced by Disseminated Cysticercosis

Cysticercosis refers to a disease caused by the larvae of <i>Taenia solium</i> parasitizing various tissues and organs of the human body. It is reported that cysticercosis is most commonly caused by the central nervous system, and retroperitoneal fibrosis is rare. We report a case of retroperitoneal fibrosis caused by cysticercosis and a urinary tract obstruction caused by retroperitoneal fibrosis, which was successfully relieved by transurethral stenting. The complex pathophysiological mechanism of cysticercosis-induced retroperitoneal fibrosis requires further study. In the diagnosis and treatment of the disease, it is very important to consider the patient's epidemiological history and the presence of parasite infection.
