Whether or not right-sided hilar enlargement is easily treated and improved depends largely on the specific etiology. The most common right-sided hilar enlargement is more commonly an inflammatory reaction, such as tuberculosis caused by infection with Mycobacterium tuberculosis, which is more commonly a primary syndrome on the right side. Primary tuberculosis belonging to the initial stage is completely curable by sensitive treatment with anti-tuberculosis drugs, such as the choice of isoniazid, rifampin, ethambutol, pyrazinamide, etc., which can completely achieve a cure. In addition, it is also seen that the right hilar enlargement is mainly associated with idiopathic interstitial pulmonary fibrosis, which can be treated with a combination of glucocorticoids and immunosuppressive drugs, which can also slow down the development of pulmonary fibrosis and lead to improvement. In addition, malignant tumors in the right hilar, such as lung cancer, can be treated with early surgical resection, radiotherapy, chemotherapy and targeted drug therapy, which can be used for early lung cancer.
