[Atraumatic splenic rupture in Legionella pneumonia].

A 48-year-old male patient was admitted to hospital with Legionella pneumonia. He developed a splenic rupture 1 day after admission, which was surgically treated. Retrospectively, the splenomegaly could already be seen by sonography on admission. An alternative etiology of the splenic rupture was excluded. The case highlights the importance of early detection of splenomegaly in patients with legionellosis. Through an early interdisciplinary presentation this life-threatening complication can be recognized in a timely manner and safely treated.
