Segmental localization of pulmonary disease

Posterior pulmonary lobe: Segmental and vascular anatomy in human specimens

“…A PPL with a deep, long superior accessory fissure can be identified on a lateral chest roentgenogram or tomogram. When inflammation or atelectasis occurs in the PPL, it is even more easily discriminated on a chest roentgenogram according to earlier reports (Kane, 1955;Parker et al, 1960;Reed, 1988). If the PPL has already been identified radiologically, the B 7 , which tends to form a common trunk with B* or B 8 in the PPL, is helpful in the bronchoscopic identification of bronchial ramification in the lower lobe.…”
