Metastatic thyroid cancer to lung. Evaluate disease. CT of the soft tissues of the neck:Images through the skull base including cavernous sinuses remain within normal limits. Paranasal sinuses and mastoid air cells are unremarkable. Images through the rest of soft tissues of the neck demonstrate no evidence of a mass or pathologic adenopathy. No residual enhancing thyroid tissue is seen.A lytic soft tissue lesion erodes the spinous process of the C6 vertebra, measuring 20 x 19 mm, previously 13 x 11 mm. This lesion lesion appears to narrow spinal canal. MRI of the cervical spine could be obtained for further evaluation. Degenerative disk disease most severely affects C5-6 and C6-7, with uncovertebral osteophytes at these levels. Limited images of the apices of the lungs again demonstrate scattered pulmonary nodules. Please review dedicated report of CT of chest for details. CT of brain with infusion.No evidence of metastatic lesion to the brain, leptomeninges or the calvarium is detected. The ventricles, sulci, and cisterns are symmetric and unremarkable. The gray-white matter differentiation is normal. There is no mass effect, midline shift, intra- or extra-axial fluid collection/acute hemorrhage. The osseous structures are unremarkable. The paranasal sinuses and mastoid air cells are clear.
1.Lytic lesion affecting the C6 spinous process may narrow the spinal canal. Cervical spine MRI can be obtained for further evaluation if indicated.2. Partial visualization of multiple pulmonary nodules. Please refer to chest CT scan day for further detail.
