[The clinical characteristics of pulmonary tuberculosis in the elderly]

Pulmonary tuberculosis remains as a significant clinical problem in the elderly. To describe age-related differences in disease manifestations, a comparison was made taking in consideration predisposing factors, clinical features, radiographic findings and diagnostic approaches in cases of pulmonary tuberculosis between two groups: equal o higher of 60 years and lower of 60 years. Elderly patients had a higher number of antecedents of previous tuberculosis and underlying diseases than younger patients. At admission, symptoms like fever and hemoptysis were more frequent in the younger group. Radiographic findings revealed that upper lung infiltrates were still common in both groups, and that elderly patients presented less pleural effusions and cavitary lesions than younger patients. Since there were differences in the clinical presentations of pulmonary tuberculosis in the elderly group, a high index of suspicion for the disease should be maintained.
