Portal Vein Thrombosis and Pyogenic Liver Abscess With Concomitant Bacteroides Bacteremia in a Patient With COVID-19 Infection: A Case Report and Brief Review

The 2019 coronavirus disease (COVID-19) can present with a wide variety of clinical manifestations, including a hypercoagulable state leading to both arterial and venous thrombosis. Portal vein thrombosis (PVT) in the setting of COVID-19 has rarely been reported in the medical literature. Pylephlebitis with concomitant liver abscess is a rare complication of intra-abdominal infection. Here, we present the case of a 49-year-old man who initially presented with intermittent fevers and generalized weakness of 1-month duration and was subsequently found to have COVID-19 infection, PVT, and Bacteroides fragilis bacteremia with associated pyogenic liver abscess. The patient was treated with intravenous antibiotics and oral anticoagulation with plan to follow up outpatient with gastroenterology in 3 months to ensure resolution of PVT and liver abscess.
