The patient went on for surgical excision of the anterior compartment of the knee. 

The histological report was of a schwannoma.

Due to histology result, and the fact there were more similar lesions, the decision was made for further examinations. The patient also recollected having a sometimes strange feeling in her ears, like "train going through her head" and that her mother's brother was operated after sudden hearing loss.

Due to the histology result, anamnestic data and the imaging findings this is most probably a case of neurofibromatosis type 2.
