Since the initial description of a FMM in 1872, various surgical approaches have been described. Posterior and posterolateral FMMs are safely removed through a standard midline suboccipital approach. Nevertheless, we still face controversy regarding the management of anterior or anterolateral lesions.<\/jats:p>\n<\/jats:sec>\n\nCase Description: <\/jats:title>\nA 47-year-old patient presented with progressive headaches, unsteadiness, and tremor.
