Dominant 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 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 کاملTumefactive multiple sclerosis plaque.
W e present a case of a large solitary demyelinating plaque in the brain masquerading as tumour. A 34 year old healthy woman presented with sudden onset of left hemiparesis. Subsequent MRI of the brain showed a single large 2.5 cm right sided enhancing lesion within the white matter of the parietal lobe (fig 1). The lesion appeared to originate from the corpus callosum. Diffusion weighted and g...
متن کاملTumefactive Multiple Sclerosis in Taiwan
BACKGROUND Multiple sclerosis (MS) is less common in Asia, including Taiwan, and some characteristics of MS in Asians differ from those of Caucasians. Tumefactive brain lesion is even rarer in MS patients. OBJECTIVE To review patients with tumefactive MS and compare them with those in other studies investigating tumefactive demyelinating lesions and our Taiwanese typical MS patients. METHOD...
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 ...
