One year follow up showed no significant interval change in the benign-looking soft tissue mass.

This case demonstrates classic findings of a peripheral nerve sheath tumor on MRI.

The combination of the above described MRI findings represents a neurogenic origin of the tumor and the lack of multiple malignant traits makes benign peripheral nerve sheath tumor the most likely the diagnosis.

Imaging alone is not enough to distinguish between schwannoma and neurofibroma, and can only be differentiated by histopathology.

The patient is not considering surgical intervals currently given the stability of the mass and lack of symptoms.
