Abstract

Lesions with central hypointensity and peripheral contrast enhancement are defined as ring-enhancing lesions. The aetiologies of ring-enhancing lesions may be various, including infections, tumours, demyelinating diseases, treatment-related conditions and hematoma. The imaging findings and their distinguishing features also vary among different ring-enhancing lesions. This review examines the magnetic resonance imaging findings of different ring-enhancing lesions and their distinguishing features.
