Large-vessel thrombosis leads to ischemia and infarction of pulmonary parenchyma, creating an ideal substrate for secondary infection with subsequent rapid tissue devitalization. Impaired perfusion prevents adequate antibiotic delivery, facilitating explosive progression of necrosis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Case description<\/jats:title>\n                    <jats:p>We report a fatal case of pulmonary gangrene in a 59-year-old man with a history of chronic alcohol abuse and prior gastric resection due to ulcer disease. Initial imaging demonstrated bilateral cavitations, while clinical deterioration despite broad-spectrum antimicrobial therapy revealed complete destruction of the left lower lobe, hydropneumothorax, and pulmonary embolism.
