MRI BRAIN WITH AND WITHOUT CONTRAST, Jun 05, 2013 09:15:00 AM

INDICATION: Malignant neoplasm of the frontal lobe.
COMPARISON: Brain MRI from 4/11/2013.

TECHNIQUE:
Multiplanar, multi-sequence MR imaging of the entire brain was performed before and after intravenous administration of gadolinium-based contrast.

FINDINGS:
-Calvarium/skull base: Previous left frontal craniotomy for resection of glioblastoma.

-Orbits: Grossly unremarkable.

-Paranasal sinuses: Retention cyst in the left maxillary sinus.

-Brain: At the site of prior resection in the left frontal lobe for glioblastoma, there is benign linear surface enhancement of the dura, scattered T2 signal abnormalities, and diffuse dural thickening. These findings are compatible with surgical/treatment changes. No enhancing lesions to suggest residual or recurrent disease. No evidence of acute abnormality. No mass effect, hemorrhage, or hydrocephalus. Grossly normal flow-related signal in the major intracranial arteries and dural sinuses.

CONCLUSION:
Stable posttreatment changes without evidence of residual or recurrent tumor.
