Thyroid cancer with metastatic brain lesions: three-month follow-up. There are postsurgical findings related to left parietal metastasectomy. There is adjacent dural thickening and blood products, but no evidence of enhancing tumor in the resection cavity. There is a 6 mm enhancing lesion along the left superior parietal lobule, which appears to have slightly more confluent in enhancement, but is unchanged in size. There is also a 2 mm focus of enhancement in the right middle frontal gyrus and right medial orbitofrontal gyrus, which are also unchanged in size. There is a non-enhancing subcentimeter nodular focus of susceptibility effect along the ependymal surface of the right caudate head. There is no evidence of intracranial hemorrhage or acute infarct. The pituitary gland appears unremarkable. There is no other abnormal intracranial enhancement. Multiple foci of T2 hyperintensity in the bilateral cerebral white matter are nonspecific, but compatible with chronic small vessel ischemic disease. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. There is mild mucosal thickening involving the anterior ethmoid air cells and bilateral mucous retention cysts of the maxillary sinuses, right greater than left. The remaining paranasal sinuses and mastoid air cells are otherwise clear. The orbits are grossly unremarkable.
1. Postsurgical findings of left parietal metastasectomy without evidence of recurrent tumor at this site.2. Subcentimeter left parietal lobe and right frontal lobe lesions are stable in size. Likewise, the non-enhancing subcentimeter nodular lesion along the ependymal surface of the right caudate head is unchanged.3. No evidence of acute infarct. I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
