Abstract
Bronchogenic lung abscess complicated by the development of a bronchoperi-toneal fistula is an extremely rare and potentially life-threatening condition. It may be associated with severe sepsis, air leakage, and often requires urgent surgical treatment supported by an interdisciplinary team and intensive care management. We present a case of an 18-year-old male patient who was transferred to our institution with a left lower lobe lung abscess, developed secondary to massive bilateral pneumonia, and complicated by bron-choperitoneal fistula formation, diffuse fibrinopurulent peritonitis, and pneumoperitoneum. Complex surgical treatment was performed, followed by intensive postoperative care. The patient was successfully discharged on the 23rd postoperative day.
