I have a mild atelectasis
I have mild atelectasis too
Can this problem be caused by having MS?
usually infection(pneumonia ,Tuberculosis or other infection)or tumor Causes Atelectasis.
what do you mean by MS? metobolic syndrome don't cause Atelectasis.
She means multiple sclerosis
Can this be caused from breathing insulation for a year?
The most common cause is post-surgical atelectasis, characterized by splinting, i.e. restricted breathing after abdominal surgery.

Another common cause is pulmonary tuberculosis. Smokers and the elderly are also at an increased risk. Outside of this context, atelectasis implies some blockage of a bronchiole or bronchus, which can be within the airway (foreign body, mucus plug), from the wall (tumor, usually squamous cell carcinoma) or compressing from the outside (tumor, lymph node, tubercle). Another cause is poor surfactant spreading during inspiration, causing the surface tension to be at its highest which tends to collapse smaller alveoli. Atelectasis may also occur during suction, as along with sputum, air is withdrawn from the lungs. There are several types of atelectasis according to their underlying mechanisms or the distribution of alveolar collapse; resorption, compression, microatelectasis and contraction atelectasis. Relaxation atelectasis (also called passive atelectasis) is when a pleural effusion or a pneumothorax disrupts the contact between the parietal and visceral pleurae.

Risk factors associated with increased likelihood of the development of atelectasis include: type of surgery (thoracic, cardiopulmonary surgeries), use of muscle relaxation, obesity, high oxygen, the lower lung segments.
I have mild atelectasis too
What symptoms have u had.  I just got CT scan shows on my report. Can u explain what u know. I’m trying to understand.  Thank you.
Yes Bonnie, I had to look the word up...no one exlains it. You just get the report. Mine says I have * clear lungs except for dependent Atelectasis. What does "dependent" mean there?
My diagnoses says flattened platelike atelectasis overlying the left mid hemidiaphragm. I had 2/3rds of the left lobe of my liver plus a big tumor surgery taken off due to cancer last year. I also smoked when I was youngfrom about 16 years to 32 years old.
Atelectasis is also known as a collapsed lung or partially collapsed lung. When a lung collapses, even partially, it affects the quality of oxygen that is carried to various organs. If the lungs are affected marginally, this condition is called mild dependent atelectasis. This is to Pat.
Hi Dolly, the key word here is still "atelectasis". The words "flattened platelike" here are just descriptive terms used by the radiologists to help their clinical colleagues to better understand the shape of the atelectasis. If the atelectasis causes you no problem, you can just leave it alone. It is no big deal.
Tumor is listed as a possible cause of atelectasis and smoking a risk factor...
