Disseminated pulmonary tuberculosis
Chronic disseminated pulmonary tuberculosis

Pathogenesis. Chronic disseminated Pulmonary Tuberculosis develops as an independent form or arises from insufficiently effective Treatment of Subacute disseminated pulmonary tuberculosis. Unlike the two previous forms, it tends to have a prolonged chronic course, with spontaneous remissions followed by exacerbations.

As a result of this course, lesions of varying duration form symmetrically in both Lungs, with scar tissue growing between them. Cavities may form against this Background.

Clinical Features and Diagnosis. The onset of Chronic disseminated tuberculosis can be acute or gradual. Body Temperature is low-grade or normal; There is a loss of appetite and reduced working capacity, and patients are sometimes troubled by sweating. Patients often attribute cough and sputum production to smoking or a cold, and do not seek medical attention. Hemoptysis occasionally occurs. The disease has an undulating course. During remission, patients feel well and perform their usual activities. Over the years, dyspnea develops, leading to respiratory failure and Chronic Cor Pulmonale.

The hemogram is normal during remission; during exacerbations, mild leukocytosis and an elevated ESR are observed. The Mantoux test is positive. If cavities form in the lungs, MTB is found in the sputum.

The chest radiograph symmetrically shows lesions of varying intensity and size, linear shadows resulting from fibrotic changes, and sometimes cavitary lesions.

If treatment is initiated in a timely manner, the patient can be cured. A chronic course leads to the progression of changes and The Development of cardiopulmonary failure.

Disseminated pulmonary tuberculosis has a clinical and radiological presentation similar to bilateral Pneumonia, Pneumoconiosis, pulmonary metastases of malignant tumors, pulmonary congestion resulting from circulatory failure, etc. Repeated sputum examinations for Mycobacterium tuberculosis are crucial to confirm the diagnosis of tuberculosis.
