Abstract

Objective: To describe the clinical, paraclinical characteristics and chest computed tomography (CT) images of the pneumonia cases caused by Staphylococcus aureus with clinical signs, and confirmed by diagnostic subclinical techniques. Subject and method: 44 patients with confirmed diagnosis of pneumonia caused by Staphylococcus aureus by culture method to isolate identification: Blood, sputum, bronchoalveolar lavage, pleural fluid with S. aureus (+) results. Method: Retrospective, descriptive, cross-sectional study. Result: Average age was 56.27 ± 19.5 years, male/female = 2.4/1; dry cough 9.1%, cough sputum 77.3%; hemoptysis 22.7%, shortness of breath 72.7%, fever (> 39ºC) 68.2%, chest pain 36.4%, average: White blood cells 15.31 ± 8.29G/L, red blood cells 3.97 ± 0.79T/L; Platelet cells 277.96 ± 8.29G/L, CRP 125.39 ± 86.19mg/l; PCT 47.58 ± 119.46ng/l. Sputum culture (+) with S. aureus: The first time 61.4%; the second 29.5%; third time 47.7%. Blood culture 1 sample (+) 40.9%; Blood culture 2 samples (+) 13.6%. Culture of bronchoalveolar lavage (+) with S. aureus 31.8% and pleural fluid 25.0%. CT scan results: Consolidation 72.7%, large nodules ≥ 3mm 45.5%; small nodules < 3mm 20.5%; cave/many caves 18.2%; lung cyst 9.1%, pneural effusion 22.7%; pneumothorax 2.3%; thickness pneural 22.7%; bronchiectasis 47.7%, pulmonary artery thromboembolism 4.5%; alveolar dilation 11.4%; large mediastinal lymph nodes 4.5%, and damage to both lungs 63.6%. Conclusion: Pneumonia caused by Staphylococcus aureus presents a variety of clinical, paraclinical and CT imaging features; features with a high frequency of occurrence play an important role in orienting and supporting the diagnosis of pneumonia caused by S. aureus.
