Cardiological examination including heart ultrasonographic analysis and dental examination did not demonstrate any pathological evidence. Skin tests for M. tuberculosis, atypical mycobacteria and Quanti-FERON TB Gold test were negative. Serum component analysis, rheumatoid factor, antinuclear antibodies, antineutrophilic cytoplasmic antibodies, immunonoglobin levels, serologic tests for hepatitis A, B, C, D, human immunodeficiency virus and common viruses did not reveal any abnormality. Finally sputum cultures in three different samples revealed the presence of Acinetobacter baumannii and the diagnosis of community-acquired pneumonia with multiple abscesses due to Acinetobacter baumannii infection were made based on this evidence. The stains were susceptible to multiple antibiotics and treatment with ciprofloxacin and amoxicillin with clavoulanic acid was initiated for a three month period of treatment. A significant clinical improvement in the patient's condition was noted only a few days later which was reflected in her laboratory investigation as well. Three months later a new computed tomography scan of the chest was obtained revealing an almost completely healed right upper lobe ( Figure 2 ). The patient remains asymptomatic until now.
