A Rare Intruder of the Biliary Tract: Gallbladder Ascariasis

Gallbladder ascariasis is a rare yet significant condition caused by the migration of Ascaris lumbricoides into the biliary system. This case report describes a 54-year-old male presenting with persistent upper abdominal pain and perianal itching. Imaging studies, including ultrasonography and MRCP, confirmed the presence of gallbladder ascariasis. Despite initial medical management with Albendazole, symptoms persisted, necessitating laparoscopic cholecystectomy. Postoperative findings revealed fragments of Ascaris lumbricoides within the gallbladder. The patient experienced complete resolution of symptoms following surgery and continued anthelmintic therapy. This report underscores the importance of considering gallbladder ascariasis in endemic regions when evaluating unexplained abdominal pain. Early diagnosis through imaging and appropriate management, including surgical intervention, when necessary, can prevent severe complications.
