Lung metastasis manifesting diffuse ground-glass opacity is a very rare pattern that is difficult to distinguish from nonmalignant pulmonary diseases. Recognition of this atypical metastases pattern and avoidance of this potential pitfall are crucial. We report a unique case of the Metastatic Pancreatic Neuroendocrine Tumor Mimicking Interstitial Lung Disease diagnosed by transbronchial lung biopsie.
