Tumefactive demyelinating lesion.
A previously healthy 31-year-old woman presented with a 2-week history of progressive left hemiparesis. MRI (figure) demonstrated a 3 cm enhancing mass in the right posterior frontal white matter with several smaller lesions in the white matter of the contralateral hemisphere and brainstem (figure, D). A stereotactic biopsy of the large lesion was performed to establish the diagnosis. This show...
متن کاملMagnetic Resonance Imaging Characteristics of Tumefactive Demyelinating Lesions
Tumefactive demyelinating lesions (TDLs) are often misdiagnosed as brain tumors. To identify imaging characteristics of TDLs for their proper diagnosis, their differences from malignant gliomas, etc., were investigated based on 3-Tesla magnetic resonance imaging (MRI) and MR spectroscopy data that was obtained from 5 patients diagnosed with TDLs in our hospital. MRI displayed a paraventricular ...
متن کاملDominant perivenular enhancement of tumefactive demyelinating lesions in multiple sclerosis.
A 51-year-old woman presented with aphasia and bifrontal MRI lesions with punctuate and vague linear enhancement (figure). She improved spontaneously but 4 months later deteriorated due to the large mass and required cranial decompression. Innumerable, perivenular enhancements perpendicular to the lateral ventricles were seen within extensive bihemispheric white matter lesions. Multiple scleros...
متن کاملProton magnetic resonance spectroscopy and diffusion-weighted imaging of tumefactive demyelinating plaque.
Proton magnetic resonance spectroscopy, diffusion-weighted axonography, and diffusion tensor tractography in a patient with tumefactive demyelination plaque (TDP) were evaluated for differential diagnosis from glioblastoma. The findings of glutamate and glutamine elevations on magnetic resonance spectroscopy and apparent tracts within the lesion on axonography and tractography were unlikely to ...
متن کامل[Magnetic resonance spectroscopy in multiple sclerosis].
Magnetic resonance spectroscopy allows in vivo neurochemical exploration of multiple sclerosis (MS) lesions and normal appearing white matter on MRI. It gives insights into pathophysiology: inflammation (increase of choline), recent demyelination (increase in lipids and choline), axonal dysfunction (decrease of NAA), gliosis (increase of myoinositol). The spectroscopic profile of lesions is not...
