R upper lobe
- superior & anterior
R middle lobe
- anterior
- between costal cartilages 4 &6
R lower lobe
- inferior & posterior
Oblique fissure
Horizontal fissure
- level of costal cartilage 4
- meets oblique fissure at MAL
Diaphragmatic surface consists of middle & lower lobes
RIGHT LUNG
1
L upper lobe
- superior & anterior
- contains the cardiac notch
L lower lobe
- inferior & posterior
Lingula
- embryonic counterpart of R middle lobe, just beneath the cardia notch
Oblique fissure
Diaphragmatic surface consists of lower lobe
LEFT LUNG
2
Bronchopulmonary segment contains the ff:
Segmental bronchus (central part)
Branch of pulmonary (central part)
Branch of bronchial artery (central part)
Tributaries of pulmonary vein
- found at periphery, as surgical landmarks during segmental lung resection
3
Ghon complex = enlarged LN + parenchymal or subparenchymal lesion near a fissure
Primary TB
4
Lung apex
Begins as small consolidation, <3cm
Secondary TB
5
Caused by dissemination by lymphatics/blood
Maybe confined to lungs (scattered multiple nodules) or spread widely to other organs
Miliary TB
6
Patchy consolidation, multilobar, bilateral, basal
S. Pneumonia, Staph, H. Influenza, Pseudomonas & coliform bacilli
Bronchopneumonia
7
Consolidation of large part or entire lobe
S. Pneumonia, Klebsiella, type II pneumococcus
Elderly, alcoholics, diabetics
4 STAGES:
1. Initial acute congestion, intraalveolar fluid, few PMN, many bacteria
2. Early consolidation/red hepatization
- PMN & fibrin in alveoli
- red (RBC), firm, airless lung
- liver-like consistency
- lasts 2-4 days
3. Late consolidation/gray hepatization
- large amount of fibrin, lessening RBC & WBC
- gray-brown lung with dry-surface
- lasts 4-8 days
4. Resolution
- after 8 days
Lobar pneumonia
8
Autosomal recessive CR gene mutation which encodes for CFTR (CF transporter) that function as chloride ion channel
Abnormally thick ️mucus production by respiratory tract & GIT
Neonates --> MECONIUM ILEUS
childhood --> STEATORRHEA, bowel obstruction
Cor pulmonale develops secondary to pulmonary hypertension
Cystic fibrosis
