Pneumobilia

      A 52-year-old man presented with fever associated with malaise and vomiting a day prior to admission. He had emigrated from Ethiopia to the United States 22 years prior and had portal hypertension secondary to schistosomiasis. A transjugular intrahepatic portosystemic shunt had been placed for variceal bleeding 4 years prior. Except for splenomegaly, the physical examination was unremarkable. He had lymphopenia and elevated serum aminotransferases (aspartate aminotransferase 194 U/L, alanine aminotransferase 164 U/L). Test for severe acute respiratory syndrome coronavirus 2 was negative. Abdominal computed tomography showed pneumobilia (Figure). Review of the medical records showed that pneumobilia had remained unchanged compared with the abdominal computed tomography scan taken 4 years earlier. With negative blood cultures, positive influenza test, decreasing aminotransferases, and clinical improvement, he was given supportive treatment and discharged.
