Fascinating world of windpipe: a case with variation and imp
The following case appears in the Journal of the Association of Physicians of India.

A 52-yr-old male presented with fever and dyspnoea since 2 months. Chest radiograph revealed left sided hydropneumothorax, subsequently diagnosed as tubercular. Patient was managed with intercostal chest tube drainage and anti- tubercular therapy.

However, due to non expanding lung and as a part of routine work-up as per surgical advise, Fibre-optic bronchoscopy (FOB) was done. It revealed an aberrant bronchus (tracheal bronchus) arising from lateral tracheal wall superior to carina.

Negotiation of tracheal bronchus with pediatric bronchoscope revealed two openings. Rest of the bronchial tree was normal, except that right upper lobe bronchus was dividing and supplying only two segments.

CT reconstruction confirmed the findings and showed that aberrant tracheal bronchus was supplying apical segment of right upper lobe. Patient meanwhile subsequently responded, and drain was removed.
