upper lung

upper lung

A functional division of the lungs which is based on differences in:
(1) Physiology:
Upper lungs have greater mechanical stress, lower lymphatic flow, higher oxygen tension and pH; and
 
(2) Pathology:
Upper lungs are more often involved by chronic granulomatous disease (e.g., tuberculosis, sarcoidosis, silicosis), hypersensitivity pneumonitis, and smoking-related disease (e.g., emphysema, respiratory bronchiolitis, pulmonary Langerhans cell histiocytosis).

Follow-up chest imaging showed the presence of bilateral confluent reticulonodular opacities and air bronchograms more conspicuous in the right upper lung, perihilar regions, and left pulmonary base (Figure 2).
Other notable achievements include the first successful bilateral upper lung lobe transplant in the UK in 2013 (on a 13 year old boy with Cystic Fibrosis) and the youngest patient in the world to receive a Berlin Heart in 2014.
Caption: Figure 1: (a-c) PET scan images demonstrate increased uptake within nodes in the aortic pulmonary window, left hilum, and a mass in the left upper lung. (d) Transesophageal echocardiography shows large cardiac mass invaded to the intra-atrial septum and right and left atrium with cystic lesion protruding to the left atrium.
Her chest X-ray suggested a nodule in the left upper lung field (Figure 1(a)), and a contrast-enhanced computed tomography (CT) scan revealed a large nodule (41 x 33 mm in size) with surrounding ground-glass opacity in the left upper lobe of the lung (Figure 1(b)).
4 years after the treatment, coin lesion of the left upper lung appeared (Figure 7).
The findings had a characteristic upper lung zone predominance sparing the lung bases and the anteromedial parts of the middle lobe and lingula (Figure 2).
Lung exam revealed decreased breath sounds in the bilateral lower lung fields with tubulovesicular sound emanating from right upper lung field.
On examination, coarse crackles were present in the left upper lung zone, his blood pressure was 100/50 mmHg, and heart rate was 72 beats per minute.
In brief, the fresh left upper lung tissues and isolated cells were obtained for observation.
The chest computer tomography (CT) revealed soft-tissue shadows in the right upper lung [Figure 1]a with enlargement of the hilar and mediastinal lymph nodes.
