title: Rare occurrence of cavitation of lung metastases following effective targeted therapy: A case report.
abstract: The metastasis of malignant tumors to the lung is relatively common; however, cavitation of metastases is extremely rare in clinical cases, and the various mechanisms are controversial. The majority of irregular metastatic cavities form naturally and are detected incidentally when patients are examined prior to any therapeutic measures. The current study presents the case of a lung adenocarcinoma patient with total cavitation of intrapulmonary metastases following effective targeted therapy at the First Affiliated Hospital of Nanjing Medical University. The morphological changes were followed up for three years. This patient presented thin-walled and smooth clean cavities, which provides an indication of the effectiveness of treatment.
