title: Multiple complete ring-shaped enhanced MRI lesions in acute disseminated encephalomyelitis.
abstract: Acute disseminated encephalomyelitis (ADEM) lesions may or may not enhance with contrast material on contrast T1-weighted magnetic resonance images (T1WI). Enhancing ADEM lesions may show varying patterns of contrast enhancement, which include nodular, diffuse nodular, amorphous, gyral, spotty and incomplete ring-like. Multiple, complete ring-shaped enhanced lesions on contrast T1WI is a rare finding in ADEM. We report such a magnetic resonance imaging (MRI) finding in a 36-year-old female patient with this disease.
