58 years Female (DOB:2/6/1958)Reason: eval for brain tumor History: dizzinessPROVIDER/ATTENDING NAME: KRISTINA K SICKER There is an extra-axial mass centered along the anterior cranial fossa along the midline which is interposed between the two frontal lobes and has a broad-base towards the planum sphenoidale, fovea ethmoidalis, medial orbital roofs and cribriform plate. It measures 26 x 31 mm sagittal dimensions and 46 x 27 mm coronal dimensions. It is heterogeneous on T2. On susceptibility weighted imaging it does not demonstrate significant susceptibility effect. It is relatively bright on T2 imaging relative to gray matter. On T1 imaging it is similar in signal intensity to white matter. There is extensive vasogenic pattern of edema involving both frontal lobes but more the left than the right side. The corpus callosum, basal ganglia, hypothalamus, thalami and internal capsules are displaced posteriorly. The pituitary stalk appears to drape over the posterior clinoid.Normal vascular flow voids are present in the distal carotid and vertebral arteries, the basilar artery and the proximal anterior, middle and posterior cerebral arteries as well as the internal cerebral veins and superior sagittal sinus.The visualized portions of the paranasal sinuses are clear. The visualized portions of the mastoid air cells are clear. The visualized portions of the orbits are intact.
A large anterior cranial fossa mass is present which most likely represents a meningioma given its appearance. Esthesioneuroblastoma neuroblastoma is a less likely consideration. There is significant mass effect and vasogenic edema associated with this mass as detailed above.
