RDG examination for inflammation of the lower respiratory tract

Anatomy
The lower respiratory tract includes:


 * larynx ,
 * trachea ,
 * bronchy ,
 * lungs.

Epiglottitis
A typical clinic + edematous epiglottis ("thumbprint sign") is displayed on a targeted lateral X-ray.

Croup
Typical clinic in a typical patient + subglottic narrowing ("steeple sign") on a targeted X-ray image in anteroposterior projection.

Bronchitis
In most cases, X-rays are not well known: rough bronchovascular drawing can also be caused by chronic changes.

Bronchiolitis
At HRCT a typical tree-in-bud - an image of a sprouting tree. Bronchiolitis is not the only one that can create this image.

Peribronchitis
Amplification of peribronchia with small peribronchial infiltrates.

Pneumonia
Inflammatory conditioning of the lung parenchyma with airy bronchograms and preserved volume of the lung parenchyma (x airiness or compression).

According to the range, it can be specified as:


 * Allar pneumonia: pulmonary wing.
 * Lobar pneumonia: pulmonary lobe.
 * Segmental pneumonia: pulmonary segment.

Bronchopneumonia
Combination of peribronchial changes and inflammatory condensation of the lung parenchyma.

Pleurobronchopneumonia
Combination of peribronchial changes and inflammatory condensation of the lung parenchyma.

Atypical pneumonia
Interstitial thickening, ground-glass in combination with infiltrates - an image that does not fall into the above categories, most often in immunocompromised patients.

lung infections _ edit source ]

 * Aspergillus: only the colonization of the pre-formed cavity.
 * Chronic necrotizing aspergillosis: cotton wool, limited deposit, thick hem.
 * Aspergil bronchopulmonary aspergillosis:
 * dilatation of central bronchi,
 * high density mucus plugs are typical,
 * bronchial wall reinforcement.
 * Bronchoinvasive aspergillosis: spreads through the bronchi, grows into the wall, tree-in-bud, thickens the bronchial wall, ground-glass, mucus plugs, the image of bronchopneumonia.


 * Angioinvasive aspergillosis: a node in the lung parenchyma with a halo (typical), later cavitating, connecting to a blood vessel.

Pulmonary tuberculosis
There is often a non-specific finding in active tuberculosis - a picture of multiple condensations in the peribronchial distribution, cavities, tree-in-bud, milliary spread, enlarged lymph nodes in the hilum and mediastinum.

Postspecific changes in elderly patients are common:


 * Peak pachypleuritis.
 * Postspecific node - typically calcification.
 * Fibrous stripes, hilarization.
 * Calcification in nodes.

Pneumonitis
Pneumonitis is a broad heterogeneous group of non-infectious inflammations of the lung parenchyma.

Important

 * In diff. Consideration is a very important clinical condition of a patient well filled out request.
 * A tumor can also be hidden behind pneumonia.
