Pulmonary hydrotuberculosis is actually caused by infection with the tuberculous bacillus, which is commonly referred to as tuberculous pleurisy. Simple tuberculous pleurisy is not contagious, because the lesions are primarily within the pleural cavity, and the pleural cavity is not connected to the outside world. Therefore, simple pulmonary hydrotuberculosis is not contagious. However, if it is accompanied by pulmonary tuberculosis, and if the examination for pulmonary tuberculosis finds tuberculous bacillus in the sputum, then it is contagious in these cases.

Tuberculosis X-ray Chest Radiograph Manifestations

If it is tuberculosis, it is generally visible on an X-ray chest film. Of course, some especially early-stage or tiny lesions might not be detected except by CT. However, typical cases of tuberculosis can be diagnosed with a chest X-ray. Often, on the chest X-ray, the apices of both lungs—the uppermost parts—might show cloud-like, vague shadowy areas that are slightly brighter than the normal lung tissue but with unclear edges. Additionally, there are some cases of secondary tuberculosis, which are more severe, featuring tuberculomas which are more evenly dense and have smoother edges. These can be seen in the lungs. However, such typical severe tuberculomas are becoming less common clinically because medications are used more promptly now, and people seek treatment in a timely manner. Cases like chronic fibrocavitary tuberculosis are becoming increasingly rare, mostly seen in older patients who have been on medication for many years.

What should be noted in the diagnosis of tuberculosis combined with AIDS?

The diagnosis of tuberculosis in individuals infected with AIDS generally involves examining certain clinical symptoms such as coughing, expectoration, low-grade fever, night sweats, and blood in sputum. Additionally, it requires analysis of specific characteristics in chest imaging, such as tuberculosis lesions identified in chest CT scans that are relatively specific. Microbial tests on sputum, such as sputum culture and acid-fast bacillus smear, are also essential. When necessary, tests for tuberculosis-infected T-cells can be conducted to provide a comprehensive diagnosis. After diagnosing concurrent pulmonary tuberculosis, anti-tuberculosis treatment is required.

Is pulmonary fibrosis always caused by tuberculosis?

Pulmonary fibrosis foci do not necessarily result from tuberculosis, although tuberculosis is a relatively common cause of such fibrosis. After tuberculosis is cured, pulmonary fibrosis foci may remain. However, in cases of general pulmonary inflammation, sometimes the lesion is not completely absorbed, which may also result in fibrosis. If the pulmonary fibrosis foci are a result of tuberculosis, there is a certain risk of recurrence. In such cases, measures should be taken to prevent recurrence, such as ensuring balanced nutrition and engaging in appropriate exercise to enhance one's resistance. These measures help prevent the recurrence of tuberculosis. Additionally, pulmonary fibrosis foci can also lead to changes in lung structure, making patients relatively more susceptible to respiratory infections. Therefore, for pulmonary fibrosis foci, it is also important to keep warm and prevent respiratory infections.

How to maintain health after recovering from tuberculosis?

Now, tuberculosis is a curable disease. Therefore, after recovering from tuberculosis, the first step in maintenance is to stay calm and not to consider oneself as a patient anymore. After recovery, one's health status is the same as before, and it is crucial to maintain a healthy mental state. Additionally, one should have a regular lifestyle, balanced nutrition; avoid overwork and staying up late; avoid smoking and drinking; actively exercise and engage in outdoor activities to enhance the body's resistance and adaptability; with changes in weather, timely adjust clothing to avoid catching cold, and actively prevent colds and so on.
