Magnetic 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 کاملMetabolite findings in tumefactive demyelinating lesions utilizing short echo time proton magnetic resonance spectroscopy.
BACKGROUND AND PURPOSE To use MR spectroscopy to aid in the diagnosis of demyelinating disease and to help differentiate tumefactive demyelinating lesions from neoplastic processes. MATERIALS AND METHODS MR imaging of the brain was obtained in 4 patients who presented clinically with focal neurologic deficits. MR imaging initially revealed parenchymal mass lesions. Single-voxel MR spectroscop...
متن کاملProton MR spectroscopy of tumefactive demyelinating lesions.
BACKGROUND AND PURPOSE Tumefactive demyelinating lesions (TDLs) can simulate intracranial neoplasms in clinical presentation and MR imaging appearance, and surgical biopsy is often performed in suspected tumors. Proton MR spectroscopy has been applied in assessing various intracranial diseases and is increasingly used in diagnosis and clinical management. Our purpose was to determine if multivo...
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 ...
