HISTORY:
Status-post resection of astrocytoma
COMPARISON STUDIES:
Brain MRI 10/31/08, 5/19/08, 5/16/07
PULSE SEQUENCES:
MR imaging was performed on a 1.5 Tesla superconducting magnet using T2,
FLAIR, T1, gradient-echo T2*, and diffusion weighted pulse sequences.
Following intravenous injection of 10 ml of MultiHance, additional T1-weighted
images were obtained in axial and coronal planes.
FINDINGS:
Again seen is the large right frontal lobe resection cavity with surrounding
FLAIR signal hyperintensity. Inferior to this is a stable extra-axial fluid
collection which is communicating with the right lateral ventricle. The
ventricular sizes are unchanged.
There are stable blooming artifacts from chronic blood products identified in
the right frontal and temporal lobes.
Redemonstration of the increased T2 and FLAIR signal in the right frontal
white matter, compatible with chronic edema versus gliosis.
No evidence of abnormal enhancement on postcontrast sequences.
IMPRESSION:
No significant change compared to multiple MRIs dating back to 5/16/07. No
definite evidence of tumor recurrence.
