Female, 50 years old, with adenoid cystic carcinoma of the tongue, presenting with slurred speech and right facial droop. Assess for cranial nerve involvement of known metastatic cancer. Motion artifact degrades some imaging sequences. Within this limitation, the following observations are made.No pathologic parenchymal or leptomeningeal enhancement is appreciated. The cranial nerves as visualized show normal morphology and are free of pathologic enhancement. Incidental note is made of a developmental venous anomaly in the left middle frontal gyrus.Diffusion-weighted images are within normal limits. No parenchymal edema or mass effect is detected. No intracranial hemorrhage or abnormal extra-axial fluid collections are seen. The ventricular system is normal in size and morphology.
1.No acute intracranial abnormality to account for the patient's symptoms.2.No evidence of parenchymal or leptomeningeal metastatic disease.3.No evidence of perineural spread of tumor.
