“…Most articles on CT findings of TTB have focused on its incidence, classification, or accompanying anomalies. To the best of our knowledge, studies illustrating the anatomical relationship between TTB and the surrounding structures have been rarely reported (3,6,9). Therefore, the purpose of this study was to classify TTB radiologically using multiplanar reconstruction and three-dimensional images obtained by MDCT and to evaluate the anatomical relationship between TTB and the surrounding structures.…”

Purpose:To propose the imaging classification of true tracheal bronchus (TTB) on multi-detector computed tomography (MDCT), and to evaluate its anatomical relationship with surrounding structures. Materials and Methods:This study included 44 patients who were diagnosed with TTB on MDCT for 6 years. We classified TTB into five types, based on the existence of the right upper lobe bronchus originating from the right main bronchus and the number of segmental bronchi of TTB. We analyzed the site of origin and the running direction of TTB based on its anatomical relationship with surrounding structures and some ancillary findings. Results: The imaging classification of TTB included Type I (47.7%), Type II (13.6%), Type III (11.4%), Type IV (25.0%), and Type V (2.0%). According to the site of origin of TTB, below the aortic arch (52.3%) and at the level of the aortic arch (43.1%) were the two main sites of origin, whereas the frequency of the site of origin above the azygos arch, at the level of the azygos arch, and below the azygos arch was 27.3%, 38.6%, and 34.1%, respectively. Considering both aortic and azygos arches, below the aortic arch and below the azygos arch were the most common sites of origin (27.3%). With respect to the running direction of TTB, in all cases, TTB passed below the azygos arch to the right upper lobe. There was no statistically significant (p > 0.05) difference in age or sex between types of TTB. Ancillary findings included tracheal stenosis (n = 2), narrowing of the right main bronchus (n = 2), luminal narrowing of TTB and bronchiectasis at the distal portion (n = 1), and a highly located azygos arch above the aortic arch (n = 2). Conclusion:The proposed imaging classification of TTB and its anatomical relationship with surrounding structures will improve our understanding of various imaging features and embryological development of TTB. Radiologists should pay careful attention to evaluation of the airway including the trachea on thoracic imaging.

“…Anomalous bronchus arising below the origin of the upper lobe bronchus is called posteparterial on the right side and posthyparterial on the left side [2]. The tracheal bronchus in our case is a displaced preparterial type -the variant most commonly reported in many series [1][2][3][4][5].…”

“…The 'supernumerary' type is a true accessory bronchus as it is associated with normal branching pattern of the upper lobe bronchus [2]. The displaced type occurs more frequently than the supernumerary one [1][2][3][4][5]. Usually, displaced tracheal bronchus ventilates the apical segment of the upper lobe on the right side and apicoposterior segment of the upper lobe on the left side.…”

Tracheal Bronchus Presenting with Recurrent Haemoptysis in an Adult Female

Abnormal bronchus arising directly from the trachea or the main bronchus is a rare developmental anomaly of the tracheobronchial tree. In general, tracheal bronchus has been reported in less than 1% of adult patients undergoing bronchoscopy with a male predominance. Tracheal bronchus is classified as -'displaced' and 'supernumerary', the former being the most common type reported. Most patients are asymptomatic; however, cases presenting with cough, haemoptysis or recurrent lung infections are not uncommon. The diagnosis is usually made through computed tomography or bronchoscopy. Awareness of this anomaly may help in timely identification or prevention of perioperative complications during general anaesthesia or resectional thoracic surgery. Herein we report a case of right-sided displaced tracheal bronchus in an adult female presenting with recurrent haemoptysis.

“…Anomalia została rozpoznana u 8 z 12 648 (0,06%) dorosłych osób z populacji tureckiej, u których wykonywano broncofiberoskopię [3]. Oskrzele tchawicze najczęściej znajduje się po prawej stronie i trzykrotnie częściej występuje u mężczyzn niż u kobiet [2][3][4]. Zazwyczaj jest odkrywane przypadkowo podczas tomografii komputerowej (TK) u osób, u których nie występują żadne objawy.…”

Nieprawidłowe oskrzele wychodzące bezpośrednio z tchawicy lub oskrzeli głównych jest rzadką anomalią rozwojową drzewa tchawiczo-oskrzelowego. Oskrzele tchawicze zostało stwierdzone u mniej niż 1% dorosłych pacjentów, którzy mieli wykonywaną bronchoskopię; a większość z nich stanowili mężczyźni. Oskrzele tchawicze może być “przemieszczone” lub “nadliczbowe”, przy czym drugi rodzaj jest spotykany częściej. U większości pacjentów nie występują żadne objawy, chociaż zdarzają się osoby skarżące się na kaszel, krwioplucie lub nawracające infekcje płuc. Nieprawidłowość jest najczęściej rozpoznawana podczas badania tomografii komputerowej lub bronchoskopii. Świadomość istnienia anomalii może pomóc w identyfikacji lub uniknięciu okołooperacyjnych powikłań podczas ogólnego znieczulenia lub zabiegu chirurgicznego klatki piersiowej. W niniejszej pracy przedstawiono przypadek prawostronnego oskrzela tchawiczego u dorosłej kobiety skarżącej się na nawracające krwioplucie.
