Pancreatic-portal vein fistula, portal vein thrombosis and liver abscesses are rare complications of acute pancreatitis which occur in the setting of localised inflammation of the pancreatic tissues and surrounding structures. We discuss a 34-year-old woman with a medical history of intermittently controlled HIV and alcohol use disorder who presents with severe epigastric pain diagnosed with acute pancreatitis. Concerning CT findings showing hypoattenuating liver lesions likely to be abscesses and multiple pancreatic pseudocysts led us to order an MRI which showed thrombosis of the portal vein, porto-pancreatic pseudocyst fistulation and cirrhotic changes. Patient was treated conservatively in the hospital and ultimately given a course of antibiotics for hepatic abscesses. Workup for new diagnosis of cirrhosis revealed positive antimitochondrial antibodies, raising suspicion for autoimmune hepatitis possibly triggered by immune reconstitution in the setting of HIV infection. Patient was discharged on oral antibiotic therapy and home antiretroviral therapy.
