71 years Female (DOB:8/9/1944)Reason: history of meningioma s/p surgery and RT. follow up imaging History: nonePROVIDER/ATTENDING NAME: STEVEN J. CHMURA STEVEN J. CHMURA The patient is undergone left parietal craniotomy for removal of an extra-axial mass involving the superior sagittal sinus. The superior sagittal sinus is not present at the craniectomy site. There is redemonstration of a fluid collection at the craniectomy site.Since the prior exam the dural thickening at the posterior aspect of the falx has increased. On axial imaging and measures approximately 24 mm with x 35 mm AP dimension on sagittal imaging measures 35 mm x 25 mm it previously on axial imaging it measured 15 mm with and 24 mm AP dimension as well as 24 x 16 mm on sagittal imaging.Within the brain parenchyma adjacent to the craniotomy site there is signal change within the subcortical white matter in a contiguous fashion which has not changed substantially since the prior exam and has not changed since the preoperative exam.Incidental note is made of partial empty sella.There is mild anterior subluxation of C1 on C2.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.The visualized portions of the paranasal sinuses are clear. The visualized portions of the mastoid air cells demonstrate opacification of the right mastoid air cells. The visualized portions of the orbits are intact.
1.Since the prior exam an extra-axial dural based mass involving the falx cerebri has enlarged.2.There is mild anterior subluxation of C1 on C2 which appears unchanged since the prior exam
