Our purpose was to characterise specific MRI findings and to determine
their value in neuro-Behcet's disease. We examined 17 patients (14 me
n, 3 women) with neuro-Behcet's disease using T1- and T2-weighted spin
-echo images and contrast-enhanced images at 0.5 T. There were 13 pati
ents (76.5%) who had single or multiple lesions. Most of these were in
the basal ganglia, brain stem or deep white matter region, giving hig
h signal on T2- weighted images and isointense or low signal on T1-wei
ghted images. In 3 cases (17.6%) there was linear high signal along th
e posterior limb of the internal capsule on T2-weighted images. This w
as considered as a potential differentiating feature of neuro-Behcet's
disease. Contrast-enhancement was seen in 17 lesions in 7 patients.
