An Interesting Case of Cholangitis.

Ascariasis is one of the most common parasitic infections in the world. It is mostly asymptomatic; however, rarely when the worms migrate to the biliary tract, they can cause biliary ascariasis. It typically presents with pain abdomen, jaundice, and fever. This case report is about a patient who presented with fever, icterus, breathlessness, loose stools, and altered sensorium but had no abdominal pain. The patient was diagnosed with biliary ascariasis using ultrasound and endoscopic retrograde cholangiopancreatography (ERCP). The patient was treated with endoscopic sphincterotomy and albendazole. The patient remained stable after 10 days. The absence of abdominal pain highlights the variability of the presentation of biliary ascariasis.
