Five Segments of the Right Upper Lobe Bronchus on Bronchoscopic Anatomy: A Rare Case Report and Review of Literature

The authors present a case of a 77-year-old female, a former smoker with a history of chronic obstructive pulmonary disease who underwent bronchoscopy for evaluation of haemoptysis. The bronchoscopy revealed an anatomical variant of the right upper lobe bronchus with five branches instead of the usual three. This case report describes a peculiar anatomical abnormality in the right upper lobe. A review of the literature related to various variants in bronchial anatomy is presented. Conclusion: Awareness of this anatomical variation provides valuable information to clinicians, particularly thoracic surgeons, to plan surgical interventions, tailor procedures, and minimise complications.
