Female, 58 years old, with metastatic lung cancer, surveillance imaging. At the site of the previous small enhancing lesion along the right superior frontal sulcus, only a focus of susceptibility is now evident. No residual enhancement is seen. A nonspecific enhancing focus within the left frontal bone is unchanged.No new pathologic intracranial enhancement is seen. No evidence of parenchymal edema, mass effect or diffusion restriction is detected. Scattered small foci of FLAIR hyperintensity within the cerebral hemispheres are nonspecific and unchanged. Ventricular size and morphology remain within normal limits.
Since the prior examination, enhancement related to the lesion along the right superior frontal sulcus has resolved. There is a small focus of susceptibility at this location. No new intracranial metastases are detected. An enhancing focus within the left frontal lobe is unchanged and nonspecific.
