“…Ghaye et al observed subsuperior bronchus with a rate of 56% on the right and 26% on the left [20]. The rate of subsuperior bronchus was found as 19.4% in 67 cases by Martín-Ruiz et al 16.4% of them were on the right side [24]. Nagashima et al reported the prevalence of subsuperior bronchus as 20.4% by assessing 270 CT examinations [25].…”

Purpose: The thracheobronchial tree has several anatomic variants, many of which are asymptomatic and are not identified until adulthood. This study aimed to demonstrate tracheobronchial branching anomalies in adult patients using chest computed tomography (CT). Material and method: Thorax CT examinations of 1000 adult patients were retrospectively evaluated. Frequencies, localizations and types of the tracheal diverticulum, tracheal bronchus, accessory cardiac bronchus, upper lobes and right middle lobe branching anomalies, subsuperior and suprasuperior bronchus, right and left isomerism, situs inversus and bridging bronchus were evaluated. Results: Tracheobronchial branching anomalies were detected in 102 of the 1000 patients (491 females, 509 males). An isolated anomaly was observed in 92 patients while 5 patients had two seperate anomalies. Preeparterial bronchi in 8 patients, left prehyparterial bronchi in 2 patients, right suprasuperior bronchi in 9 patients, right subsuperior bronchi in 33 patients, left subsuperior bronchi in 38 patients, and accessory cardiac bronchi in 7 patients were observed. A single right tracheal bronchus, posteparterial bronchus, right tracheal diverticulum, upwardly displaced middle lobe bronchus, and situs inversus were found. Out of the detected congenital tracheal bronchial anomalies, 11 were displaced and 82 were supernumerary. Conclusion: Radiological assesment of the branching anomalies is crucial due to the potential clinical consequences. CT is a successful imaging method in the evaluation of tracheobronchial branching anomalies. Using lobe-based classification will facilitate the detection and classification of these anomalies.

“…Maki et al [23] observed an additional bronchi (B*) in 129 (24.0%) patients undergoing CT imaging. Martín-Ruiz et al [9] (previously mentioned in the context of anatomical variations of the lungs) provided quantitative information about B*: it occurred in 19.4% of cases, mainly on the right side (most in the right lower lobe, then the right upper lobe). Similar results were obtained by Nagashima et al [63] from 3D-CT images of patients with changes in the respiratory system or mediastinum before surgery.…”

“…The quoted number of left lung segments (8)(9)(10) varies [1,3,5] because the medial (S7) and anterior basal (S8) segments are combined into an anteromedial segment (S7+S8), while the apical (S1) and posterior (S2) segments together give the apicoposterior segment (S1+S2) [6]. This occurs because the anterior and medial segments originate from a single branch of the lower lobe bronchus [2].…”

“…Martín-Ruiz et al [9] studied anatomical variations of the lungs by dissecting the lungs of 17 cadavers and examining bronchoscopies of 50 hospital patients. Only 37.31% of lung pairs showed no variability [9]. In this study, the right lower lobe showed the highest percentage variability; the middle and left lower lobes showed the lowest.…”
