A 19-year-old African American woman presented to the emergency department with a history of left upper quadrant pain for a week, associated with nausea, malaise, loss of appetite, subjective fevers and chills. Her family history is significant for thalassemia in her maternal aunt, and hereditary spherocytosis in her brother, sister and cousin. A contrast-enhanced CT scan of the abdomen and pelvis revealed massive splenomegaly and multiple splenic infarcts. On the second day of admission, she developed a fever of 103°F. Further evaluation revealed acute Epstein-Barr virus (EBV) infection and hereditary spherocytosis. Her condition improved after 4 days on piperacillin/tazobactam, intravenous fluids, analgesics and antipyretics. Our case report describes a thorough clinical evaluation of a patient with fever, anaemia, massive splenomegaly and multiple splenic infarcts. It highlights the need for careful interpretation of multiple positive IgM results on viral serological testing that often accompanies acute EBV infections.
