Splenic abscess?,”Splenic abscess usually presents with the classic triad of fever, leukocytosis, and left upper-quadrant abdominal pain. Patients can also develop left-sided pleuritic chest pain, left pleural effusion, and splenomegaly. Risk factors for splenic abscess include hematogenous spread, immunosuppression, IV drug use, trauma
and hemoglobinopathies. Infective endocarditis is most commonly associated with splenic abscesses.”
