A man with no history of trauma had localized wheeze and rhonchus in the left side of his chest. Clinical diagnosis of partial obstruction of the left main bronchus was confirmed by bronchoscopy and planography. Surgery revealed complete fracture of the left main stem with high-grade fibrous stricture between the fractured ends. Resection of the stenotic area with end-to-end anastamosis was performed. Questioning revealed trauma from a jeep accident 22 years earlier as the only source of the lesion.
