Findings
Heterogeneously enhancing mass within the right frontal operculum (inferior frontal gyrus pars opercularis), measuring 2.8 x 2.9 x 2.9 cm (anteroposterior by transverse by craniocaudal).
Surrounding T2 FLAIR hyperintense signal likely reflecting a combination of nonenhancing infiltrative tumor and vasogenic edema, with minimal leftward subfalcine herniation and right uncal herniation, though without cerebellar tonsillar herniation.
DSC perfusion leakage corrected relative cerebral blood volume map demonstrates markedly increased blood volume to the mass relative to the normal brain parenchyma.
No areas of restricted diffusion (remote from the mass) to suggest acute infarct. No acute intracranial hemorrhage or extra-axial collection.
Gray-white matter differentiation is otherwise preserved. Ventricular size within normal limits for patient age. Major intracranial flow voids intact. Partially empty sella turcica.
Paranasal sinuses and mastoid air cells clear aside from mucous retention cyst within the left maxillary sinus. Orbits normal. Scalp and calvarium unremarkable aside from frontotemporal scalp fiducial markers.
Impression
Right frontal opercular mass, likely a high-grade glioma.
