Pulmonary gangrene with vascular occlusion

Area of Science:

• Pulmonology
• Radiology
• Pathology

Background:

• Pulmonary gangrene is a rare and severe lung condition.
• Understanding its radiographic and microscopic features is crucial for diagnosis and management.

Observation:

• Sequential roentgenographic changes were observed in three cases of pulmonary gangrene.
• These changes provide characteristic patterns for identifying the disease progression.

Findings:

• Microscopic examination revealed endarteritis obliterans in all three cases.
• This finding suggests a vascular component in the pathogenesis of pulmonary gangrene.
• The current series expands the literature to 14 reported cases.

Implications:

• The study highlights the importance of correlating imaging findings with histopathology.
• Further research into the etiologic factors of pulmonary gangrene is warranted.
• Improved diagnostic criteria may lead to earlier intervention and better patient outcomes.
