Gallbladder ascariasis complicated by chronic eosinophilic cholecystitis in a one-year-old infant: A case report

Although uncommon, Ascaris lumbricoides may migrate into the gallbladder, resulting in symptomatic cholecystitis. In endemic regions, gallbladder ascariasis should be considered in the differential diagnosis of patients with unexplained gastrointestinal or biliary symptoms. Early recognition through a high index of suspicion and timely ultrasonographic evaluation is essential for accurate diagnosis and optimal management. Peripheral eosinophilia, reflecting the host immune response to parasitic infestation, may provide an additional diagnostic clue.
