Female, 64 years old, with stage III recurrent non-small cell lung cancer presenting with vague neurologic symptoms (weakness) rate assess for brain metastases. Image quality on several sequences, including the postcontrast sequences, is degraded by motion artifact. Within this limitation, the following observations are made.No definite pathologic parenchymal or extra-axial enhancement is observed. No focal edema or mass effect is seen. Diffusion-weighted images are within normal limits. A small nonspecific focus of FLAIR hyperintensity is seen within the right inferior parietal lobule. A small slitlike defect is also seen in the left cerebellum.No evidence of acute intracranial hemorrhage or any abnormal extra axial fluid collection is seen. The ventricles are normal in size and morphology.
1.Within the limitations of a motion degraded exam, no evidence of metastatic disease is seen.2.A small chronic left cerebellar infarct is noted.
