Tuberculoma refers to the organism by tuberculosis bacillus infection after the formation of tuberculosis, serious lung tissue damage calcification and the formation of foci, is not a tumor, generally not serious, but in the immune deficiency there is a possibility of transformation into disseminated, active tuberculosis, or even malignant, will be more serious. The lesion mostly exists singly, with a diameter of more than 2 cm. The most typical pathological change of pulmonary tuberculosis is caseous necrosis, which is a round or oval lesion formed by fibrous tissue surrounding and wrapping around it, and it is a benign infectious lesion, not a real tumor, so it is not serious in general. When the body’s immunity decreases, the tuberculosis tumor liquefies and dissolves to form a cavity, which develops into infectious active tuberculosis or disseminated tuberculosis; because of the external fibrous wrapping, the anti-tuberculosis drugs, such as isoniazid, rifampicin, etc. are not easy to play a role, and there is a possibility of malignant transformation. If you have symptoms such as severe cough and blood in sputum, you should consult a doctor promptly.
