Pulmonary nodules with explosive calcification were finally diagnosed as lung adenocarcinom: A case report

This case emphasizes that nodules with diffuse, popcorn-like calcification do not rule out the possibility of lung cancer. A comprehensive evaluation integrating multidimensional imaging features is necessary. For nodules with conflicting imaging characteristics, minimally invasive surgical resection remains valuable for diagnosis. This approach broadens our diagnostic perspective on calcified nodules, enhances clinicians' understanding of lung adenocarcinoma, and reduces the rate of misdiagnosis.
