Department of Pediatrics Gustave Roussy Institute Villejuif, France We present the clinical observation of a 16-month-old girl treated for a posterior fossa ependymoma who experienced severe and delayed visual dysfunction. She was initially treated by surgery and conventional chemotherapy. When she relapsed at age 3 years, the salvage treatment combined high-dose chemotherapy, second surgery, and local irradiation. At age 4 years, disturbed gait and dysarthric speech appeared rapidly, and she became unable to recognize objects and people. Computed tomography revealed bilateral calcifications in the cerebellum and temporal and occipital lobes but no relapse. The neuropsychologic evaluations revealed signs of visual agnosia and marked intellectual impairment. The role of the different treatment modalities in the pathogenesis of this unusual syndrome is discussed. (J Child Neurol 2001;16:698-704).
