ABSTRACT

Primary leptomeningeal melanomatosis is an exceptionally rare entity and represents a challenge for diagnosis in a clinical setting; however, in magnetic resonance this disorder appears as diffuse and linear signal hyperintensity in the leptomeninges in T1 sequences, which is the diagnostic key which suggests the presence of melanin and helps differentiate it, as well as other tumors affecting the leptomeninges.
