Perilesional Hyperintensity on T1-Weighted Images in Intra-Axial Brain Masses other than Cavernous Malformations.

Background And Purpose: Hyperintensity on T1-weighted imaging in perilesional vasogenic edema has been reported as a useful sign for differentiating cavernous malformation from other hemorrhagic intra-axial masses. In this study, we investigated the frequency of perilesional hyperintensity on T1-weighted imaging in patients with intra-axial hemorrhagic and nonhemorrhagic brain masses.

Methods: The study was performed with the approval of the institutional review board.

The impact of pontine disease on lower urinary tract symptoms in patients with multiple sclerosis.

Aims: To investigate the relationship between pontine lesion characteristics on MRI and lower urinary tract symptoms (LUTS) in patients with multiple sclerosis (MS).

Methods: We performed a prospective cohort study of patients with MS and LUTS who were undergoing brain/spine MRI. Patients were administered the American Urological Association Symptom Score (AUA-SS), Medical, Epidemiologic, and Social Aspects of Aging questionnaire (MESA), and Urogenital Distress Inventory questionnaire (UDI-6), underwent Kurtzke Expanded Disability Status Scale (EDSS) scoring by a neurologist, and had their MRIs reviewed by a neuroradiologist.
