Analysis Of Misdiagnosis Reason Of Pulmonary Peripheral Spherical Lesions

Objective: Improve the diagnostic accuracy of the pulmonary spherical lesionswhich were misdiagnosed after imaging examination. Methods: The clinical symptomsand medical imaging data of85cases with pulmonary spherical lesions misdiagnosedwere analyzed retrospectively. Results:85pulmonary spherical lesions misdiagnosed inthe study,36cases of lung cancers were misdiagnosed as pulmonary tuberculosis (23cases), inflammatory pseudotumor (12cases), pneumonia (4cases) and pleuralmesothelioma(2cases);32cases of pulmonary tuberculosis were misdiagnosed as lungcancers(23cases); inflammatory lesions (7cases), hamartoma (2cases);10cases ofPulmonary hydatid were misdiagnosed as lung cancer(3cases)、pulmonary tuberculosis (5cases) and inflammatory pseudotumor(2cases);5cases of inflammatory pseudotumorwere misdiagnosed as lung cancer(1cases) and pulmonary tuberculosis (4cases);2casesof pulmonary hamartoma were misdiagnosed as pulmonary tuberculosis. Hemoptysis,lobulated sign, density, cavitation sign, and satellite foci had statistical significancebetween benign and malignant of the misdiagnosis of peripheral pulmonary sphericallesions (P＜0.05). Conclusion: The misdiagnosis of pulmonary spherical lesions could bedecreased by analyzes examination and clinical manifestation attentively, and applieslogical examination methods.
