Abstract

We present two rare lumbar lesions with similar MRI features: high signal on T1-weighted and proton density images and low signal on T2-weighted images; a melanotic schwannoma, and a giant-cell tumour-like lesion. Melanin in the first case and haemosiderin and metahaemoglobin in the second were responsible for the MRI characteristics.
