63-year-old man with non-small cell lung cancer with metastases to brain. Presented with seizure and right-sided paralysis. No new seizures on medications. Improved right sided strength with Decadron. Evaluate status of brain. The left frontal metastasis (series 2 image 23) now measures 1.0 x 0.8 cm compared to 1.0 x 0.9 cm on study dated 6/30/2008. The amount of peritumoral edema is stable from CT dated 7/31/2008 slightly increased from the study dated 6/30/2008. A smaller left frontal lesion visible on MRI is once again not seen on the CT.The right frontal metastasis (series 2 image 18) now measures 1.2 x 0.8 cm compared to 1.4 x 0.8 cm on the prior study. The amount of peritumoral edema is stable from the study dated 7/31/2000.The left temporal metastasis seen on the MRI is still not clearly visible on CT. The associated peritumoral edema has stable CT appearance from the prior study.The metastatic lesion in the cerebellar vermis is not visible on CT.There is no mass-effect, midline shift, hydrocephalus, or CT evidence of hemorrhage. 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.
1. Multiple brain metastases with peritumoral edema stable from study dated 7/31/2008. Peritumoral edema remains increased from study dated 6/30/2008.
