1 Dural and intracranial extension of mass.
Dural and intracranial extension of mass. A, Axial T2-weighted scan demonstrates soft-tissue mass infiltrating the anterior cranial fossa with associated edema of the right frontal lobe. B, Parasagittal T1-weighted scan shows the gross infiltration across the cribriform plate to involve the anterior cranial fossa with massive involvement in an extra-axial location. C, Postcontrast fat-suppressed T1-weighted scan shows intracranial extension as well as dural infiltration and pial extension of tumor adjacent to the midline. D, A different patient with adenocarcinoma of the paranasal sinuses shows considerable thickening of the dural greater than 5 mm, indicative of dural infiltration, confirmed at surgery. D.M.
