Post-COVID-19 syndrome mimicking cholangiocarcinoma: A case report.

Patients with severe coronavirus disease 2019 (COVID-19) manifest liver injuries with pathological changes because of lowered blood oxygen saturation, cardiac malfunction, hepatotoxic drugs during treatment, and cellular injury. This paper reports a patient with a history of severe COVID-19 who mimics cholangiocarcinoma after undergoing endoscopic retrograde cholangiopancreatography (ERCP). It was shown that differential diagnosis of post-COVID-19 syndrome is greatly important mostly in patients with symptoms of biliary obstruction.
