Rare Cervicothoracic Intramedullary and Extramedullary Lipoma.

We report a rare case of cervicothoracic intramedullary and extramedullary lipoma. Complete resection of the extramedullary lipoma and almost complete resection of the intramedullary lipoma were performed using a microscope, followed by posterior fusion and internal fixation from C4-T2 to maintain the stability of the cervicothoracic junction. Despite the high risk, it was still necessary to perform the decompression surgery and the surgical results were favorable.
