Abstract
Background HIV is known as a risk factor for venous thromboembolic events. However, portal vein thrombosis is rare among HIV infected patients. Few cases have been described in the literature. Case presentation We report a case of abdominal pain in a 25-year old HIV-positive man with a low CD4 count and co-infection with hepatitis B. The pain existed since four days. Computed tomography showed portal vein thrombosis and anticoagulation therapy was initiated. Conclusion This case provokes questions about the etiology of portal vein thrombosis in HIV-positive patients and might determine risk factors. It emphasizes the importance of considering portal vein thrombosis as a cause of abdominal pain in HIV infected patients, in particular when they have low CD4 counts or co-infection with hepatitis B. In addition, HIV and viral hepatitis should be considered in patients who present with thrombotic events.
