“Pulmonary nodules and pulmonary nodular disease are two different concepts. Pulmonary nodulopathy is a granulomatous disease with pulmonary involvement due to invasion of the lungs by nodular disease, characterised by non-caseating, epithelioid chronic granulomas.
Pulmonary nodules, on the other hand, are a common clinical sign of a round or irregular shaped lesion less than or equal to 3 cm in diameter in the lung, which is shown on imaging as an increased density shadow, either solitary or multiple, with clear or indistinct borders. The two can be differentially diagnosed by performing a lung puncture.
In addition, pulmonary nodular disease does not usually require treatment if the symptoms are not severe, with the possibility of spontaneous remission, or if it is more severe, it requires treatment with glucocorticoids. Lung nodules, on the other hand, do not require treatment if they are benign nodules, or surgery and radiotherapy if they are malignant.”
