17 years Male (DOB:7/24/1998)Reason: evaluate for residual tumor History: s/p tumor and seizure focus resectionPROVIDER/ATTENDING NAME: PAULA L ZAKRZEWSKI JASON M KANE Since the prior exam patient is undergone right-sided craniotomy and right temporal lobectomy for a right temporal lobe mass. 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.There are blood products along the path of a previously placed in depth electrode as well as within the temporal lobe resection site. There are some superficial enhancement along the surface of the brain at the surgical site.A small extra-axial hemorrhagic collection is present adjacent to the depth electrode insertion site measuring about 7 mm in thickness and 38 mm in width. Another extra-axial collection of blood is present adjacent to the right frontal and parietal lobes at the surgical site measuring up to 5 mm in width.There is a scalp soft tissue swelling along the right parietal and frontal scalp as well as edema within the right temporalis muscle.The visualized portions of the paranasal sinuses demonstrate mild mucosal thickening. The visualized portions of the mastoid air cells are partially opacified. The visualized portions of the orbits are intact.
Status post right temporal lobe surgery. There are blood products at the surgical site and along the extra-axial spaces adjacent to the craniotomy and burr hole sites. There is no convincing evidence for residual neoplasm. Please note however, that postoperative changes may mask a tiny nodule on MRI. The follow-up exam would be helpful in further evaluating for residual or recurrent tumor.
