Female, 62 years old, with history of T1 N0 left tongue squamous cell carcinoma status post resection and lymph node dissection on 05/20/16, now with falling down and shaking extremities. Brain:Scattered foci of T2 hyperintensity are again seen within the cerebral hemispheres and the pons showing no significant interval change from prior. No edema or mass effect is detected. No pathologic intracranial enhancement is observed. Diffusion-weighted images are within normal limits. No findings to suggest intracranial hemorrhage or any abnormal extra-axial fluid collections are demonstrated. Ventricular size and morphology are within normal limits.Neck:Deformity of the left oral tongue is seen compatible with interval surgery. No discrete mass or definite pathologic enhancement is seen within the oral tongue. Mild, ill-defined T2 hyperintense signal along the left floor of mouth is nonspecific but probably related to surgery as well.Evidence of left neck dissection is seen. The left submandibular gland has been removed. No pathologic adenopathy is identified. The residual salivary glands and the thyroid are unremarkable. Bone marrow signal characteristics are within normal limits. Persistent opacification of the left sphenoid sinus is again seen. A 7 mm T1/T2 hyperintense lesion at the midline of the thyroid lobe may represent a thyroid nodule or a thyroglossal duct cyst.
1.No acute intracranial abnormality or evidence of intracranial metastases. Scattered foci of nonspecific T2 hyperintensity are unchanged and perhaps related to chronic microvascular ischemia.2.Postoperative findings are seen in the neck with no evidence of recurrent tumor or pathologic adenopathy.
