37 years, Male, glioblastoma multiforme diagnosed in June 2006, status post resection in 2006 and January 2013. Status post radiotherapy and chemotherapy. There is a right parieto-occipital lesion with T2 hyperintensity extending into the temporoparietal and occipital lobes, probably combination of tumor and vasogenic edema, unchanged from prior. This mass contains numerous foci of susceptibility consistent with hemorrhage, not substantially changed from prior MRI. This mass extends across the midline involving the splenium of the corpus callosum and ependymal surface of the left lateral ventricle, unchanged. There is effacement of the occipital horn of the right lateral ventricle, unchanged from prior. There is a 4 mm right to left midline shift, unchanged. A right occipital resection cavity is again identified. There is no evidence of acute infarction. There is no hydrocephalus. There is an area of nodular enhancement within the right occipital lobe measuring 1.7 x 0.7 cm, probably subacute hemorrhage, unchanged from CT July 10, 2015.Sella and orbits are grossly within normal limits. Paranasal sinuses and mastoid cells are clear. Bone marrow signal is within normal limits. A right posterior occipital lipoma is unchanged.
1.Unchanged large enhancing, hemorrhagic right hemispheric glioblastoma multiforme that extends into the left corpus callosum and along the left lateral ventricle. Unchanged 4 mm right to left midline shift.2.Unchanged right posterior occipital subacute intratumoral hemorrhage identified on prior CT July 10, 2015.3.Unchanged right occipital lobe resection cavity and radiation changes.
