Reason: evaluate for structural lesion in setting of seizrues and headaches History: seizures and headaches The CSF spaces are appropriate for the patient's stated age with no midline shift. There is a 20 x 10 mm axial dimensions extra-axial left parafalcine mass adjacent to the left frontal lobe which was also identified on the previous exam last July and is not appear to have changed dramatically. It is bright signal on T1 and low signal on T2 and dark on susceptibility imaging. There is no substantial contrast enhancement associated with this.The hippocampi are symmetric.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.
1.There is no significant change compared to the previous exam. There is remonstration of a small left parafalcine lesion adjacent to the left frontal lobe which appears to be calcified.
