MR imaging of diffuse glioma.
Neuroradiologic diagnosis of "gliomatosis cerebri" is hampered by the diffuse, isodense character of the lesion, and the fact that it may not enhance when intravenous contrast medium is administered. Clinical signs and symptoms are usually nonspecific, nonfocal, and disproportionately mild. We report a case of diffuse glioma in a 30-year-old man, discuss the difficulty in arriving at a precise ...
متن کاملLow-grade glioma: correlation of short echo time 1H-MR spectroscopy with 23Na MR imaging.
BACKGROUND AND PURPOSE There is considerable variability in the clinical behavior and treatment response of low-grade (WHO grade II) gliomas. The purpose of this work was to characterize the metabolic profile of low-grade gliomas by using short echo time (1)H-MR spectroscopy and to correlate metabolite levels with MR imaging-measured sodium ((23)Na) signal intensity. Based on previous studies, ...
متن کاملGlioma grading: sensitivity, specificity, and predictive values of perfusion MR imaging and proton MR spectroscopic imaging compared with conventional MR imaging.
BACKGROUND AND PURPOSE Sensitivity, positive predictive value (PPV), and negative predictive value (NPV) of conventional MR imaging in predicting glioma grade are not high. Relative cerebral blood volume (rCBV) measurements derived from perfusion MR imaging and metabolite ratios from proton MR spectroscopy are useful in predicting glioma grade. We evaluated the sensitivity, specificity, PPV, an...
متن کاملMR of isolated leptomeningeal glioma.
We report the MR study of a case of high-grade glioma that mimics leptomeningeal carcinomatosis. Superficial gliomas should thus be included in the differential diagnosis of isolated meningeal enhancement.
متن کاملMR of malignant optic glioma of adulthood.
A case of malignant optic glioma of adulthood is imaged in its early and late stages with high-resolution MR. The images show the mass to arise from the right optic nerve before invasion of the optic chiasm.
