This is one of the most common findings on a chest x-ray.
It is most often caused by an endobronchial lesion, such as mucus plug or tumor. It can also be caused atelectasis radiology extrinsic compression centrally by a mass atelectasis radiology as lymph nodes or peripheral compression by pleural effusion.
An unusual type of atelectasis is cicatricial and is secondary to scarring, Atelectasis radiology, or status post radiation. Atelectasis is almost always associated with a linear increased density on chest x-ray.
The apex tends to be at the hilum. The atelectasis radiology is associated with volume loss. It is frequently seen in chronic lung disease.
Multifocal Multifocal consolidations are also described as multifocal atelectasis radiology opacities or densities. In most cases these are the result of airspace-consolidations due to bronchopneumonia.
As mentioned before bronchopneumonia starts in atelectasis radiology bronchi and then spreads into the lungparenchyma. This can lead to segmental, diffuse atelectasis radiology multifocal ill-defined densities.
In some cases however the underlying pathology of multiple ill-defined densities is interstitial disease, like in the alveolar form of sarcoidosis in which the granulomas are very small and fill up the alveoli. First study the chest x-ray.

What are atelectasis radiology findings and what is the atelectasis radiology diagnosis? Notice that there are multiple densities in both lungs. The larger ones are ill-defined and maybe there is an air-bronchogram in the right lower lobe.

Probably we are dealing with multifocal consolidations, but one might also consider the possibility of atelectasis radiology ill-defined masses. There is a peripheral distribution. This patient had a several month atelectasis radiology of chronic non-productive cough, that did not respond to antibiotics.
So we are dealing atelectasis radiology the differential diagnosis of chronic consolidation. The lab-findings were normal which makes bronchoalveolar carcinoma and lymphoma less likely.
There was no eosinophilia, which excludes eosinophilic pneumonia. Wegener's granulomatosis Wegener's is a collagen vascular disease with vasculitis involving the lung, kidney and sinuses.
Atelectasis radiology the lung the vasculitis causes infarcts which first present as ill-defined areas of consolidation. In a later stage these infarcts become more circumscribed and can be seen as multiple nodules or masses, sometimes with cavitation. Atelectasis radiology a patient with non-specific findings.
