Proton 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 کاملCase Series: tumefactive demyelinating lesions: a diagnostic challenge.
T umefactive demyelinating lesion (TDL) is defined as a solitary de myelin ating lesion greater than 2 cm. Mass effect and contrast enhancement on neuroimaging make it difficult to distinguish this type of lesion from high-grade gliomas. Multiple sclerosis (MS) accounts for most cases of TDL. Even in patients with established MS, an atypical manifestation of a large lesion can suggest concurren...
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 کاملTumefactive demyelinating lesions: spectrum of disease, diagnosis and treatment
Whenever MRI imaging depicts typical small, ovoid, well-circumscribed T2 hyperintense lesions scattered across periventricular, iuxtacortical and infratentorial white matter along with a clinical scenario highly suggestive of inflammatory-demyelinating disease of CNS (CNS IID), multiple sclerosis (MS) diagnosis is straightforward. Nevertheless, the expanding role of MRI in MS evaluation is para...
