69-year-old female with a history of glioblastoma multiforme presents with generalized weakness. There is redemonstration of a large right frontotemporal lobe mass involving the insula consistent with patient's biopsy proven glioblastoma multiforme. There is hypodensity surrounding this mass consistent with a combination of tumor infiltration and vasogenic edema. Periventricular white matter hypoattenuation also noted. These findings appear similar to the prior studies though MRI would be more accurate for evaluation of tumor progression.There is no evidence of a new intracranial mass or focal lesion. There is no evidence of acute territorial ischemia. There is no acute intracranial hemorrhage or extra-axial fluid collection. While there remains 4mm of right to left midline shift, the sulci and ventricles appear slightly more prominent than in November 2011, probably on the basis of treatment related change (e.g. steroids). There is no basal cistern effacement or herniation.Right frontal bone burr hole. The remainder of the calvaria and skull base are radiographically normal. The visualized mastoid air cells are clear. Partial opacification of the ethmoid sinuses bilaterally. Bilateral lens prosthesis.
1. No acute intracranial abnormality.2. Right frontotemporal mass with surrounding edema, similar to the previous examination when allowing for differences in modalities. No significant interval change in associated leftward midline shift. MRI examination would be more sensitive for evaluation of tumor progression.
