72 years Female (DOB:8/9/1944)Reason: s/p crani for tumor History: s/p crani for tumorPROVIDER/ATTENDING NAME: KRUPA G ANDALKAR PETER C. WARNKE Since the prior examination patient is undergone parietal craniotomy for removal of an extra-axial mass involving the superior sagittal sinus. The lobulated enhancing component remaining along the anterior aspect of the mass measuring 33 x 19 mm in axial dimensions the superior sagittal sinus appears to be patent adjacent to it.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 preoperative exam.There are are some small foci of diffusion restriction adjacent to the surgical site within the brain parenchyma. There are some blood products which are hyperintense on T1 at the surgical site. There is soft tissue swelling present involving the scalp tissues.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 examination the patient is undergone partial removal of an extra-axial mass adjacent to the falx and superior sagittal sinus. There are associated postoperative changes present.2.There is mild anterior subluxation of C1 on C2 which appears unchanged since the prior exam
