A 71-year-old woman presented with a rare case of geriatric ependymoma originating from the fourth ventricle manifesting as progressive gait and memory disturbance. Imaging studies revealed an extraaxial mass in the fourth ventricle protruding into the right cerebellomedullary cistern, with concomitant obstructive hydrocephalus. Surgery achieved subtotal removal since the tumor tightly adhered to the right vestibular area of the fourth ventricular floor. The histological diagnosis was ependymoma, which was also confirmed by comparative genetic hybridization. Although she developed severe laryngeal edema and worsening of the hydrocephalus postoperatively which required additional treatment, she recovered with residual mild gait disturbance, and was transferred to a rehabilitation facility. Fourth ventricle ependymoma in the elderly is rare. Comparative genetic hybridization may be important in the diagnosis of geriatric ependymoma and in the choice for adjuvant therapy as well as in estimating the prognosis for patients with rare types of ependymoma.
