Pre op planning for surgical resection of brain tumor. There is a centrally low T1 and high T2 hemorrhagic lesion that measures up to 4.5 cm in the left frontal lobe. There is also a low T2 signal along margin of the right lateral ventricle body that measures up to approximately 15 mm. The ventricles and basal cisterns are unchanged in size and configuration. There is unchanged mild midline shift to the right. Skin fiducial markers are present.
Treatment planing MRI for a left frontal lobe hemorrhagic lesion, which may represent a metastasis. A lesion along margin of the right lateral ventricle body may also represent a hemorrhagic metastasis.
