The following diseases need to be differentiated for bronchopulmonary cancer: tuberculosis, pneumonia, lung abscess, mediastinal lymphoma, benign lung tumors, and tuberculous exudative pleurisy. The differential diagnosis is also based on the patient’s general condition such as gender, age, past history, and relevant ancillary tests.
Bronchopulmonary cancer and other lung diseases have similar imaging morphological manifestations and similar clinical symptoms. For patients with bronchopulmonary cancer, the main differential diagnoses are: 1. Tuberculosis: Tuberculosis usually has symptoms such as low-grade fever, night sweats, and a multi-year history. Positive tuberculin test, effective anti-tuberculosis quality treatment, etc.
2. Pneumonia: Patients with pneumonia may have shadows in the lungs that disappear after treatment with antibiotics, but if there are recurrent infections in the same area and antibiotic treatment is not effective, it may be lung cancer.
3. Lung abscess: Lung abscess has clinical manifestations such as rapid onset, chills and high fever, coughing and coughing up purulent sputum.
4. Benign lung tumors: The differential diagnosis requires the assistance of chest CT and PET-CT, and a definitive determination requires pathological examination.
5. Mediastinal lymphoma: usually bilateral, with systemic symptoms such as fever. The diagnosis can be confirmed by lymph node biopsy and other methods.
