Lung abscess caused by Streptococcus constellatus: Case report
Abstract
This case report presents a detailed case study of Lung abscess caused by Streptococcus constellatus. This case underscores the critical role of accurate microbiological diagnosis in the effective management of lung abscesses, highlighting the necessity for precise identification and targeted treatment strategies. A 47-year-old male who exhibited persistent fever and mucopurulent cough, leading to a visit to the Emergency Department of a local hospital in Riobamba, Ecuador. Initially, the patient was diagnosed with pneumonia and treated with moxifloxacin and itraconazole. However, as his condition deteriorated, he was transferred to a specialty hospital in Quito, Ecuador. Chest X-rays identified a cavitary lesion, which was further confirmed by CT chest imaging to be a lung abscess. Additional diagnostic work through CT-guided biopsy and culture confirmed the presence of Streptococcus constellatus. The patient's treatment regimen included targeted antibiotic therapy with piperacillin-tazobactam, resulting in a six-week hospitalization. The patient's condition significantly improved, and he was subsequently discharged.
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
