Basic Syndrome Concepts

Primary complex obvious.

Etiology and pathology of primary syndrome

For the first infection of tuberculosis, the human body inhales dust or droplets containing tuberculosis from the air and becomes ill. Occurs in children or young people, especially infants under 3 years old. Primary syndromes include primary lesions and peri-inflammatory lesions, lymphangitis, and lymphadenitis, and sometimes additional localized pleural changes.

Clinical manifestations of primary syndrome

Fever, cough, shortness of breath, night sweats, and weight loss are the main clinical symptoms. Some cases may be asymptomatic and found by physical examination. A sputum test can detect tuberculosis.

Imaging findings of primary syndrome

1. The lower part of the upper lobe or the upper part of the lower lobe is flaky or round-like fuzzy shadow, and it can also show the lung segment or lobe shadow. 2. Ipsilateral hilar lymph nodes are enlarged.

3. A cable-like shadow can be seen between the primary lesion in the lung and the enlarged hilar lymph nodes, that is, tuberculous lymphangiitis.

The above three are dumbbell-shaped, also known as the bipolar phase, which are typical manifestations of the primary syndrome, but such signs are rare. If the scope of the primary lesion is large, tuberculous lymphangitis and lymphadenitis can often be masked.

Differential diagnosis of primary syndrome

Primary tuberculosis cavities are distinguished from acute lung abscess cavities, the latter of which has a more uniform density, and a clear fluid level is often seen in the cavity.
