Biliary Strongyloides stercoralis With Cholecystitis and Extensive Portal Vein Thrombosis

Abstract

We report the rare finding of Strongyloides stercoralis rhabditiform larvae in biliary fluid, here associated with cholecystitis and near total portal vein thrombosis. The role of S. stercoralis leading to atypical clinical presentations and difficulty diagnosing strongyloidiasis in such patients with appropriate geographic exposure is discussed.

Case Report: Two Cases of Strongyloidiasis Presenting with Thrombotic Events

“…Certain parasitic infections incite eosinophil upregulation of prothrombotic surface molecules and degranulation and secretion of inflammatory factors that may predispose to thrombosis distant from the site of parasitized tissue. 11 On literature review, the described mechanisms may have contributed to the other reported cases of strongyloidesassociated thromboses: biliary strongyloidiasis causing local parasitism and portal vein thrombosis, 12 and left ventricular thrombus related to endomyocardial fibrosis due to high eosinophilia and S. stercoralis hyperinfection. 13 Treatment.…”

Hepatocellular Carcinoma and Strongyloides Infection with Portal Vein Thrombosis

“…There are a few case reports published about biliairy strongyloides infection, 2-4 but only one with also portal vein thrombosis. 5 In this case the tumor marker deteriorates after treatment of the strongyloides infection. The treatment seems to have a positive effect on the tumor.…”
