Darkening in the lungs on x-ray – what can it be?


  • What to do with detection of spots on an x-ray?
  • Often informative survey of the state of the lungs prescribed x-rays. His conduct can be shown to Refine the data of chest x-ray or clinical picture of the patient. As for diseases of the lung tissue density in the affected areas, usually elevated, x-rays will show the location of the picture spot. When the patient, examining the resulting x-ray, sees her spots, the first thought that comes to mind: cancer. What does the darkening in the lungs on radiographs, what could it be? And why do they occur?

    Why white spots appear on x-ray?

    Reasons for the appearance in the picture of the white spots can be different factors:

    For a more complete picture of the pathological process, in addition to direct, make more images in the lateral and oblique projections. Each spot, localized on x-ray, the doctor evaluates a number of parameters:

    • The location of the blackout. It can be placed in the upper region of the lung tissue, the middle and at the bottom. In addition, conventionally, light is divided into the inner zone, middle and outer. This gives you the opportunity in the future, a clearer picture of the pathology.
    • Size. Refinement of this parameter allows to set the area of the pathological process in the lungs.
    • The degree of severity. On this basis, determine the density of the lesion. The spot on the image can have a highly pronounced intensity, weak or average.
    • The outlines dimmer. On what contours has a slick, smooth or uneven, clearly expressed or not, is determined, for example, the nature of the tumor or tumors.

    There is another classification of spots on x-ray, according to which there are the following different types of blackouts.

    Equity dimming

    In this type of spot perfectly visible its outline on x-ray. It may be convex, having a concave or linear shape. Such a blackout in the lung may take place in case of any chronic process. This may be a purulent process, or cirrhosis, a destructive disease of the bronchi.

    As a rule, cancer and benign lead to stains in the lower and middle area of the body.

    Patchy darkening

    Such spots on the lungs are not too large, about 1 cm They may indicate only the beginning of an inflammatory or other process. In addition, the appearance in the picture such blackouts may indicate pathology of the vessels. Because of the uncertainty causes, the doctor usually refers the patient for further examination (e.g., CT, blood test, x-ray sighting).

    Focal shadows in the lungs can speak about the presence of peripheral cancer, pulmonary infarction, focal tuberculosis and other diseases. High temperature, headache, cough and chest pain in combination with similar x-ray pattern, suspicious for bronchopneumonia. And pulmonary infarction symptoms of heart disease, herkenham blood, manifestations of thrombophlebitis.

    Blackout indefinite form

    For such spots is characterized by the absence of any particular form and severity of outline. For an accurate diagnosis is required for additional blood tests and urine tests, and use of other diagnostic methods (e.g. CT). Disease, in which the x-ray appear an indefinite white spots:

    • pneumonia;
    • pulmonary infarction;
    • pleurisy;
    • bleeding;
    • tumor and others.

    In the diagnosis of great importance are the laboratory data and the clinical picture of the disease.

    Liquid blackout

    Sometimes in the lungs may occur swelling of the tissues. If the pressure in the vessels increases, the possible exit of liquid from them in the alveolar apparatus body. In addition, a number of toxic substances which can disrupt the permeability of the alveolar wall. In this case, the liquid also gets into the lung tissue. In light liquid violates the functional activity of the organ.

    Such pathology that occurs most often in violation of the cardiovascular system, manifested in the picture dimming.

    Segmental dimming

    If it has the form of a triangle, this indicates such diseases as:

    • cancer;
    • the benign one;
    • inflammation of the lungs;
    • the presence of metastasis from other organs;
    • tuberculosis;
    • the presence of fluid in the pleural cavity and so on.

    Mandatory for the correct diagnosis prescribe additional comprehensive examination. Of great importance in this case have the experience and competence of the doctor.

    Focal dimmable

    Presents round single spots of about 1 cm Can be in diseases such as:

    • inflammation of the lungs;
    • increased fluid content;
    • the TB (it’s a tuberculoma);
    • cysts;
    • abscesses.

    Sometimes they are evidence of the presence of cancer or benign tumors (lipoma, adenoma). In any case, it is necessary to conduct additional tests.

    What to do with detection of spots on an x-ray?

    If you have discovered the picture dark or light dimming, no need to panic. The best solution in this situation would not picture painting a terrible future, and strict adherence to doctor’s instructions.

    Basically, when it detects dark areas on x-ray requires a careful examination. Find out from the physician what other methods of diagnosis can provide the information needed for diagnosis, and complete them. Also ask what diseases or disorders can give the same picture. Maybe the reason is hidden in another place.
