This case was pathologically proven to be a spinal neurofibroma.

Spinal neurofibroma are difficult/impossible to categorically distinguish from spinal schwannomas, both usually show a T1 hypointense signal, T2 hyperintense signal ​and heterogenous enhancement.

Schwannomas are frequently associated with hemorrhage, intrinsic vascular changes (thrombosis, sinusoidal dilatation), cyst formation and fatty degeneration, but these features are not always present. 

Portuguese: Este caso corresponde a um neurofibroma intramedular comprovado após ressecção cirúrgica.
