Pneumothorax

collapsed lungtension pneumothoraxpunctured lung
It is often called a collapsed lung, although that term may also refer to pneumothorax. Relaxation atelectasis (also called passive atelectasis) is when a pleural effusion or a pneumothorax disrupts the contact between the parietal and visceral pleurae.

Ectasia

Ectasisectasiasectatic
The term uses combining forms of atel- + ectasis, from ἀτελής, "incomplete" + ἔκτασις, "extension".
Ectasia, also called ectasis, is dilation or distention of a tubular structure, either normal or pathophysiologic but usually the latter (except in atelectasis, where absence of ectasis is the problem).

Pulmonary surfactant

Acute atelectasis may occur as a post-operative complication or as a result of surfactant deficiency.

Chest radiograph

It is a very common finding in chest x-rays and other radiological studies, and may be caused by normal exhalation or by various medical conditions.
A decrease implies hypoventilation, as can occur with restrictive lung disease, pleural effusions or atelectasis.

Pulmonary alveolus

alveolialveolarpulmonary alveoli
It is a condition where the alveoli are deflated down to little or no volume, as distinct from pulmonary consolidation, in which they are filled with liquid.
Insufficient surfactant in the alveoli is one of the causes that can contribute to atelectasis (collapse of part or all of the lung).

Bronchiectasis

bronchectasisbronchiectasiadilated
In chronic atelectasis, the affected area is often characterized by a complex mixture of airlessness, infection, widening of the bronchi (bronchiectasis), destruction, and scarring (fibrosis). The blocked, contracted lung may develop pneumonia that fails to resolve completely and leads to chronic inflammation, scarring, and bronchiectasis.
The complications of bronchiectasis include serious health conditions, such as respiratory failure and atelectasis.

Pleural cavity

It is usually associated with accumulation of blood, fluid, or air within the pleural cavity, which mechanically collapses the lung.

Flat-chested kitten syndrome

One possible cause for flat chestedness that develops soon after birth is atelectasis.

Pneumonia

The blocked, contracted lung may develop pneumonia that fails to resolve completely and leads to chronic inflammation, scarring, and bronchiectasis.
Pulmonary infiltrates that resolved after giving mechanical ventilation should point to heart failure and atelectasis rather than pneumonia.

Bronchiole

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).
