Objective: To heighten our awareness of pneumonia of Legionnaires' disease (LP).
Methods: 37 cases of LP were reviewed.
Results: Besides the characteristics of pneumonia, extrapulmonary manifestations, including gastrointestinal, hepatic, renal and neurologic abnormalities, occurred in 35% of the patients, pleural effusion was more common (40%), 38% and 17% of the patients showed hyponatremia and pulmonary abscess respectively. Roentgenographic changes appeared to last longer and resoluted later than the clinical improvement occurred.
