    Interesting pictures! ))))
    I don’t think that this MRI signal is artifact from metal as this artifact appears just in T1 FS poscontrast.. I have no idea, but I would be happy to read the right answer )))
    I think that it’s intradural extramedullar mass.

    1. It is a metal artifact from the microchip. It is unusual that it’s not readily apparent on other sagittal images.
    2. The mass is intradural-extramedullary – Note the “golf tee” sign on the sagittal T2-weighted image
    3. Histologic diagnosis following surgical excision was meningioma. Other differentials based on MRI included malignant nerve sheath tumor, lymphoma, histiocytic sarcoma, metastatic tumors, and other less common neoplasms. Focal inflammatory/infectious disease (e.g., fungal granuloma) also possible.
