Spinal neurofibroma

Discussion:

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.
