Strongyloides Stercoralis infection mimetizing pancreatic pseudotumor in immunocompetent patient

Abstract

Strongyloides stercoralis is one of the most prevalent species of parasites in the world and isconsidered endemic in Latin America. Strongyloides stercoralis is an intestinal parasite, transmitted by soil and highly prevalent in hot regions with inadequate sanitation. Commonly reported symptoms of strongyloids infestation include diarrhea, vomiting, abdominal pain, hives, and "larva currens". In the present report, a man without comorbidities, with no immunosuppressive conditions, developed an exuberant clinical picture, whose infection spread in a way to cause uncommon clinical manifestations, such as intestinal ulcerations, running with duodenal stenosis and pancreatic pseudo tumor. The diagnosis was made by computer tomography and histopathological examination of duodenal lesions. After the antiparasitic treatment, the patient evolved with complete remission of gastrointestinal symptoms, of imaging findings and with adequate nutritional recovery. Although pancreatic involvement related to Strongyloides stercoralis infection is a rare condition, should be considered as a diferential diagnosis in pancreatic pseudotumors.
