Cornules in both lungs refers to rice-sized lesions found in both lungs, and there is another level of meaning that both lungs are sprinkled with rice-sized lesions. Most commonly, as in tuberculosis, when hematogenous dissemination of tuberculosis occurs, the manifestation is diffuse small rice-grain-sized nodular lesions scattered in both lungs, called hematogenous tuberculosis. Of course, there are also other manifestations, such as occupational diseases, coal miners or gold miners, and other patients who have been exposed to dust for a long time, because of excessive dust inhalation, which also manifests itself in the lungs as corn-grain sized lesions. There are many other conditions, such as interstitial lung lesions, which can be cords, lattices, or nodular lesions the size of a corn. There are also pulmonary metastases, which in the early stages of hematogenous metastases are also relatively small nodular lesions, like corn grains sprinkled inside the lungs. Therefore, the exact nature of the lesion needs to be analyzed by a combination of imaging, clinical and laboratory tests.
