The severity of striated and nodular hyperdense shadows in the upper lobe of the left lung needs to be differentiated according to the severity of pneumonia, tuberculosis, lung cancer, and previous lung diseases.
1. Pneumonia is the most common disease that can cause striated and nodular hyperdense shadows, which can be effectively controlled with scientific anti-infection treatment and is relatively mild in severity.
2. Tuberculosis, the infection of tuberculosis bacillus, can cause localized density increase and similar manifestations, usually can be controlled by anti-tuberculosis treatment, but need about 6 months of treatment, the condition is relatively serious.
3. Lung cancer, which is the most serious cause of lung cancer, can cause metastasis if treatment is not timely, and the average 5-year survival rate is 15%~17%, which is a more serious condition.
4. Previous lung diseases, such as previous history of tuberculosis, can cause localized old tuberculosis foci, the condition is relatively mild, usually no obvious symptoms.
The specific cause of the disease needs to be clarified after medical examination, and treatment should be taken according to the doctor’s instructions.
