58 years Male (DOB:9/2/1957)Reason: brain lesion History: brain lesionPROVIDER/ATTENDING NAME: BEN-ZION ROITBERG BEN-ZION ROITBERG There is redemonstration of a T2 heterogeneous mass within the right half of the suprasellar cistern measuring 20 x 17 mm axial dimensions which abuts and partially surrounds the right internal carotid artery supraclinoid segment and extends into the interpeduncular cistern and prepontine cistern where it abuts the basilar artery and the right posterior cerebral artery. This mass is higher signal on FLAIR MRI in the low signal on T1 and somewhat heterogeneous on T1 imaging. There is no significant susceptibility effect associated with it. It displays heterogeneous enhancement following gadolinium administration. This mass is also identified on the CT scan from 7/14/2014 and is not appear to have changed substantially in dimensions.The CSF spaces are appropriate for the patient's stated age with no midline shift. 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.
There is a mass centered in the right half of the suprasellar cistern which extends into the interpeduncular cistern and prepontine cistern which partially surrounds the right internal carotid artery and abuts the basilar artery and the right posterior cerebral artery as well as the right superior cerebellar artery and the right cranial nerve III. This does not appear to have enlarged substantially since 2014. It is uncertain what this represents.
