Unexpected metastasis of thyroid cartilage involvement from lung adenocarcinoma: A case report

Figure 3 The imaging of the case. A: Axial computed tomography (CT) with contrast image shows nodules in the left piriform sinus with bone destruction of the thyroid cartilage; B: Magnetic resonance imaging shows nodules in the left piriform sinus; C: CT with contrast image shows peripheral type lung cancer in the left upper lobe; D: Positron emission tomography-CT images. Imaging confirmed widespread metastases involving hilar/mediastinal/supraclavicular/cervical lymph nodes, bilateral adrenals, and multiple bones (spine and thyroid cartilage).
