Bartonella henselae infection mimicking a splenic lymphoma.

We report a Bartonella henselae infection in a 40-y-old patient who presented with fever, weight loss, night sweats, elevated lactate dehydrogenase and multinodular splenomegaly with multiple abdominal lymphadenopathies. Splenic cat-scratch disease is an exceptional diagnosis in adults and can easily be mistaken for a splenic lymphoma, thereby leading to an unnecessary splenectomy.
