Multidisciplinary Management of Multi-Compartmental Infections in an Immunocompromised Patient: A Case of Retropharyngeal Abscess, Empyema, and Chest Wall Abscesses

This case study presents a 43-year-old male with poorly controlled diabetes and recent hepatitis B diagnosis who developed extensive infections involving the retropharyngeal space, left pleural cavity, and right chest wall. His condition was further complicated by chronic granulomatous lymphadenitis. The patient's initial refusal of surgery led to prolonged morbidity, requiring coordinated medical intervention across departments. Imaging, drainage, and targeted antibiotics yielded substantial improvement over six months. The case underscores the complexities of managing polymicrobial infections in immunocompromised hosts and highlights the value of integrated, patient-centered treatment strategies when surgical approaches are limited.
