A 13-yr-old male with fever, malaise, body pains and dry cough.

Abstract

A previously healthy 13‐yr‐old male was evaluated at La Spezia Hospital, La Spezia, Italy, because of a 15‐day history of fever, malaise, body aches and dry cough, which were not modified by treatment with amoxicillin. A summary of the first admission blood tests is shown in table 1⇓. The chest radiograph and the high-resolution computed tomography (HRCT) scans performed at that time are shown in figure 1a–c⇓. Treatment with ampicillin, teicoplanin and netilmycin was administered for 7 days followed (as a result of no significant clinical response) by 12 days i.v. therapy with ciprofloxacine and imipenem-cilastatine. The apyretic patient was discharged on oral ciprofloxacin. However, 2 weeks later, he was referred to the Giannina Gaslini Institute, Genoa, Italy, for further evaluations due to the recurrence of fever and dry cough.

View this table: Table 1— Blood test results for the patient's first and second admission On second admission, the patient's body temperature was 37.8°C, his respiratory rate was 28 breaths·min−1 and transcutaneous O2 saturation in room air was 98%. Blood test results are shown in table 1⇑. Chest radiograph and HRCT scans are shown in figure 2a–c⇓. Fibreoptic bronchoscopy did not demonstrate any airway abnormality. Bronchoalveolar lavage (BAL) analysis showed as follows: 1) increased neutrophil percentage (35%); b) no acid-fast bacilli, viruses, fungi or malignant cells; and 3) positive cultures for Streptococcus mitis and S. milleri . Microscopic examination of transbronchial-biopsy specimens obtained from the right lower lobe showed interstitial nonspecific lymphocyte infiltration. Treatment with ampicillin-tazobactam and vancomycin was prescribed for 10 days, with only slight improvement of the clinical and laboratory parameters but no further changes in the chest radiographs. A diagnostic surgical procedure was performed and …
