Something is wrong with multiple nodules in the lungs, consider lung cancer, benign lung nodules, metastases from other tumors in the lungs, possible tuberculosis, and should be actively consulted to improve chest CT, PET-CT to further clarify the diagnosis.
Multiple nodules in the lung are first considered as possible malignant tumors in the lung if the nodules are large in size and have burrs at the edges with unclear borders, and the patient may have symptoms such as coughing, coughing up sputum, wasting and hoarseness. If the nodule in the lung is small with smooth margins, benign nodules may be considered.
The nature of the nodule is clarified by pathological puncture biopsy. If the size is small and there are no corresponding respiratory symptoms, those whose imaging does not support malignant lesions for the time being should be followed up with regular review of chest CT to observe changes in the nodule. If the nodule is a malignant tumor, whole-body PET-CT should be improved to clarify whether the lung is the primary lesion, and if it is the primary lesion but no distant metastasis, surgery may be considered.
If the patient also has symptoms such as low-grade fever and night sweats, consider the possibility of cornified tuberculosis, which can be diagnosed by antacid staining, PPD test, and culture of Mycobacterium tuberculosis.
