 X-rays are not as effective in the monitoring or evaluation of enchondromas due to frequent localized changes also sometimes due to the large number of enchondromas.Magnetic resonance imaging (MRI) can sometimes however be used to monitor and evaluate symptomatic lesions in the case of potential malignant transformations.Similar disorders such as Maffucci syndrome and hereditary multiple exostoses (HME) require differentiation during diagnosis.
