What is a left lower lobe consolidation?
Left lower lobe consolidation refers to consolidation in part (incomplete) or all (complete) of the left lower lobe.
What causes lower lobe consolidation?
Consolidation refers to the alveolar airspaces being filled with fluid (exudate/transudate/blood), cells (inflammatory), tissue, or other material. The list of causes of consolidation is broad and includes: pneumonia. adult respiratory distress syndrome (ARDS)
What does consolidation on the lung mean?
Lung consolidation occurs when the air that usually fills the small airways in your lungs is replaced with something else. Depending on the cause, the air may be replaced with: a fluid, such as pus, blood, or water. a solid, such as stomach contents or cells.
Is lung consolidation cancerous?
If the invasion or destruction of the mesenchyme of the lung is minimal, air in the lung remains within the lung cancer, resulting in a ground glass appearance on thin-section CT. Thus, consolidation on thin-section CT could be strongly associated with the invasiveness of lung cancer [4].
Is lung consolidation the same as pneumonia?
It is important to be aware that consolidation does not always mean there is infection, and the small airways may fill with material other than pus (as in pneumonia), such as fluid (pulmonary oedema), blood (pulmonary haemorrhage), or cells (cancer).
What is the lower lobe of the lung?
The Lower Lobe (Right Lung) The lower lobe is the bottom lobe of the right lung. It lies beneath the oblique fissure. It bears medial, lateral, superior, anterior, and posterior bronchopulmonary segments.
What is the function of the left lung?
According to York University, the right lung is shorter because it has to make room for the liver, which is right beneath it. The left lung is narrower because it must make room for the heart. Typically, a man’s lungs can hold more air than a woman’s.
What are the symptoms of lobar pneumonia?
Lobar pneumonia may present with a productive cough, dyspnea, pyrexia/fevers, rigours, malaise, pleuritic pain, and occasionally hemoptysis. Key features on physical examination are dullness to percussion in a lobar pattern, bronchial breathing, and adventitious breath sounds.
Does consolidation mean pneumonia?
What causes lower lobe pneumonia?
The most common organisms which cause lobar pneumonia are Streptococcus pneumoniae, also called pneumococcus, Haemophilus influenzae and Moraxella catarrhalis. Mycobacterium tuberculosis, the tubercle bacillus, may also cause lobar pneumonia if pulmonary tuberculosis is not treated promptly.
What is the anatomy of the left lower lobe?
Left lower lobe 1 Gross anatomy. Like all the pulmonary lobes, it is lined by visceral pleura which reflects at the pulmonary hilum where it is continuous with the parietal pleura. 2 Blood supply. Venous drainage of newly oxygenated blood is via the right inferior pulmonary vein into the left atrium. 3 Lymphatic drainage. 4 Innervation
How is the left lower lobe of the lung separated?
The LLL is separated from the left upper lobe posterosuperiorly by the left oblique fissure. Like all the lobes of the lung, the LLL has dual arterial supply:
What are the features of left lower lobe consolidation?
Features of left lower lobe consolidation on CXR include: opacification of the mid and/or lower zones, and occasionally even upper zone normal (clear and distinct) left superior mediastinal contour (silhouette sign), especially the aortic arch obscuration of the left hilum, particularly the inferior hilum in apical segment consolidation
Where is the left lower lobe bronchus located?
Location and structure. The left lower lobe bronchus arises as the inferiorly angled continuation of the left main bronchus to traverse the left hilum into the LLL. The LLL is separated from the left upper lobe posterosuperiorly by the left oblique fissure.
