Capillary telangiectasia mimicking an active inflammatory MS-lesion in repetitive cMRIs

Abstract:

Repetitive cranial magnetic resonance imaging (MRI) showed lesions typical of multiple sclerosis (MS) with one Gd-enhancing focus in the left parietal cerebrum which correlated to the clinical symptoms of a secondary progressive female MS patient. Since this Gd-enhancing lesion lasted over more than two years even after numerous intravenous high-dose methylprednisolone administrations and intrathecal triamcinolone injections the infl ammatory etiology of this lesion was questioned and T2* echo-gradient images and MR angiography showed a capillary telangiectasia mimicking an active infl ammatory MS-lesion.
