From the anatomic perspective, a normal LUL bronchus divides into an upper division bronchus and lingular bronchus. 2 Lung parenchyma supplied by the lobar bronchus has its complete overlying pleura. Is the LUL bronchus in Figure 5B of the article by Mehta et al 1 a true lobar bronchus or, in fact, the upper division of the LUL bronchus— a sublobar bronchus? Th e discrimination is important bec...

introduction: the diagnosis of foreign bodies in the upper aerodigestive tract is usually straightforward but sometimes it can be delayed or the location of esophageal and upper airway foreign bodies can be mistakenly interchanged.  case report: we present two interesting cases that caused diagnostic challenges which could have led to serious complications if a greater delay in diagnosis had oc...

pulmonary agenesis is a very rare condition and many of them are associated with a variety of cardiac and non-cardiac malformations. we report an eight-month old girl with chronic lung infection due to right sided pulmonary agenesis without any associated major cardiac or non-cardiac abnormalities. the case brings in forth the importance of investigating any infant presenting with features of c...

A 42-year-old man was diagnosed with cancer of the right lower lung lobe with a posteparterial type of tracheal bronchus, in which the posterior segmental bronchus of the right upper lobe arose from the distal bronchus intermedius. A mass involved the distal bronchus intermedius, requiring a right lower bilobectomy with an additional posterior segmental resection of the right upper lung lobe. T...

INTRODUCTION Tracheal bronchus is a right-sided anomalous bronchus arising from the trachea above the main carina and occurs in 0.1% to 2% of the general population. CASE PRESENTATION We present a case of left main bronchus obstruction during a left-sided double-lumen tube intubation in a patient with an unrecognized tracheal bronchus. After the intubation, to confirm the position of the tube...

A 75-year-old woman with no history of skin tumors came to our clinic complaining of hemoptysis lasting for three months. Chest computed tomography (Picture 1A) and an image of the left main bronchus on virtual endoscopy (Picture 1B) demonstrated endobronchial polyps in the left main bronchus and proximal portion of the lingular bronchus. Bronchoscopy revealed two polypoid tumors arising from t...
