Cystlike white matter lesions in tuberous sclerosis.
PURPOSE To investigate the presence of small cystlike structures in the cerebral hemispheric white matter on MR images of patients with tuberous sclerosis. METHODS The MR images of 18 consecutive patients with tuberous sclerosis were reviewed retrospectively. RESULTS Eight of the 18 patients were found to have cystlike structures in the cerebral white matter. The signal intensity of these l...
متن کاملWhite Matter Diseases YES, Multiple Sclerosis NO, Sjogren - Larsson Syndrome: Another Differential Diagnosis of Multiple Sclerosis
Sjogren-Larsson Syndrome (SLS) is an inherited autosomal recessive neurocutaneous disorder with congenital ichthyosis, spastic diplegia or quadriplegia and mental retardation. We report a case of Sjogren-Larsson Syndrome with clinical profile (mental retardation, ichthyosis, spastic diplegia) and MRI findings such as seen in multiple sclerosis (MS). So this rare syndrome can be another differen...
متن کاملWhite-matter lesions drive deep gray-matter atrophy in early multiple sclerosis: support from structural MRI.
BACKGROUND In MS, the relationship between lesions within cerebral white matter (WM) and atrophy within deep gray matter (GM) is unclear. OBJECTIVE To investigate the spatial relationship between WM lesions and deep GM atrophy. METHODS We performed a cross-sectional structural magnetic resonance imaging (MRI) study (3 Tesla) in 249 patients with clinically-isolated syndrome or relapsing-rem...
متن کاملThe effect of hypointense white matter lesions on automated gray matter segmentation in multiple sclerosis.
Previous imaging studies assessing the relationship between white matter (WM) damage and matter (GM) atrophy have raised the concern that Multiple Sclerosis (MS) WM lesions may affect measures of GM volume by inducing voxel misclassification during intensity-based tissue segmentation. Here, we quantified this misclassification error in simulated and real MS brains using a lesion-filling method....
متن کاملCorrelation between white matter damage and gray matter lesions in multiple sclerosis patients
We observed the characteristics of white matter fibers and gray matter in multiple sclerosis patients, to identify changes in diffusion tensor imaging fractional anisotropy values following white matter fiber injury. We analyzed the correlation between fractional anisotropy values and changes in whole-brain gray matter volume. The participants included 20 patients with relapsing-remitting multi...
