All CT scans were acquired with 64\u2010slice scanners. Atypical bronchi in the RLL were classified on the basis of running direction and shape: lateral (Lat), posterolateral (PL), posterior (Post), Lat\u2009+\u2009PL, and PL\u2009+\u2009Post. We classified an atypical bronchus in the basal segmental bronchus (BSB) stem running posteriorly or posterolaterally as B* and a para\u2010lateral bronchus running laterally as Para\u2010B8. The B* posts running posteriorly were named P1, and those running medially P2.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Atypical BSB bronchi Lat, PL, and Post arose from B8, B9, and B10, respectively. All Lat\u2009+\u2009PL bronchi arose from B8 or B9, and all PL\u2009+\u2009Post from B9 or B10. When an atypical bronchus arose from one of the BSB pair, none arose from the other. Atypical bronchi forming B* and Para\u2010B8 arose from the stem spreading the connatural BSBs. The P2 post coexisted with another atypical stem bronchus originating from B8, 9, 10, or higher.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>The first subsegmental bronchi of B8, B9, and B10 are Lat, PL, and Post, respectively. Lat\u2009+\u2009PL and PL\u2009+\u2009Post bronchi at the BSB level could result from fusion of an atypical bronchus during downward migration. The stem B* and Para\u2010B8 could result from arrested downward migration of atypical bronchi.
