Uncommon presentations of ascariasis: A case series including gallbladder ascariasis and Löffler’s syndrome

Gallbladder ascariasis is an uncommon manifestation of ascaris lumbricoides infection, typically seen in the endemic regions. Even rarer is the concurrent presence of Löffler’s syndrome. We report the two cases – the first, a 92-year-old male, presented with typical biliary colic and was diagnosed with gallbladder ascariasis. The second, a 38-year-old female, presented with respiratory symptoms and was found to have ground-glass opacities on high-resolution computed tomography and peripheral eosinophilia, later associated with gallbladder ascariasis on imaging. Both cases were managed conservatively with anthelminthic therapy and supportive care. This series highlights both the hepatobiliary and pulmonary presentations of ascaris lumbricoides infection.
