Abstract

Introduction: Focal ground-glass opacity on computed tomography suggests several disorders including inflammatory disease, fibrosis, or a primary lung neoplastic lesion, metastatic lung tumor.

Case presentation: The case of a 55-year-old female presenting with adenocarcinoma of the lung is herein reported. Computed tomography of the chest revealed a primary mass lesion in the upper lobe of the right lung and multiple metastases presenting as ground-glass opacities. Macroscopic metastases were observed in the bone, the hilar and mediastinal lymph nodes, and another lobe. This case was advanced lung cancer. We assumed that the multiple ground-glass opacity lesions were metastasis in the lungs. Chest CT revealed a partial response of the primary site and the multiple ground-glass opacities after systemic chemotherapy.

Conclusion: A metastatic lung tumor showing ground-glass opacity is uncommon. It is quite difficult to distinguish between multiple primary lung cancers and intrapulmonary metastasis when patients present with multiple lung nodules. A lot of clinical information is therefore required to make an accurate diagnosis in such cases.
