67-year-old female with history of small cell lung cancer status post chemo/RT. History brain metastases status post resection and whole brain RT. There is a questionable focus of mild enhancement or intrinsic high density along the superior aspect of the left lateral ventricle approximately at the location of the corpus callosum. This finding is slightly more conspicuous than was seen on prior study dated 7/2/2008. This is suspicious for metastatic focus. MRI is recommended to evaluate this finding.Patchy areas of low attenuation in the subcortical and periventricular white matter reflect small vessel ischemic disease. Stable area of encephalomalacia is seen in the left parietal lobe vertex adjacent to the craniotomy site.There is no evidence of intracranial hemorrhage or edema.The ventricles and basal cisterns are normal in size and configuration.The calvaria and skull base are radiographically normal. The visualized paranasal sinuses and mastoid air cells are normally pneumatized.
Questionable area of enhancement above the roof of the left lateral ventricle. MRI pre-and post contrast is recommended to further evaluate.
