Abstract
A 58-year-old female had a 1-year history of headache, ataxia, and taste disturbance and then developed speech disturbance. She was found to have a meningioma of the fourth ventricle, a very rare site for this type of tumor. It did not adhere to the cerebellar tentorium or dura mater and was totally removed without difficulty. Magnetic resonance imaging, but not computed tomography or angiography, provided adequate information for correct diagnosis. The literature concerning fourth ventricle meningiomas is reviewed and the diagnostic advantages and limitations of computed tomography, angiography, and magnetic resonance imaging are discussed.
