27 years Female (DOB:5/8/1989)Reason: prior lesion in right occipital lobes (restricted diffusion, high T2 signal, mild enhancement), evaluate for evolution History: headachePROVIDER/ATTENDING NAME: HELENE G. RUBEIZ SERVICES ANCILLARY There is a 19 x 37 mm axial dimension cystic lesion anterior to the left temporal lobe which is associated with some mild expansion of the adjacent bony structures. This most likely represents an arachnoid cyst. It follows spinal fluid on all pulse sequences.Previously noted punctate lesion in the right occipital lobe is no longer visualized.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.
