Core Tip

Core Tip: Single organ vasculitis (SOV) of the gastrointestinal (GI) tract is uncommon with hepatic artery involvement rarely reported. It presents with abdominal pain and often without changes in inflammatory or other biomarkers. It is diagnosed radiographically or incidentally via surgical specimens. mRNA coronavirus disease 2019 (COVID-19) vaccines have been stipulated to contribute to inflammatory side- effects such as myocarditis, and autoimmune hepatitis. The diagnosis of GI SOV should be considered as a potential cause of acute abdominal pain following COVID-19 mRNA vaccination.
