MALIGNANT OPTIC GLIOMA OF CHILDHOOD
Abstract
Optic glioma is known as a tumor of childhood. However, malignant glial tumors of the anterior visual fi›athway are rarely encountered in children, but in the elderly. The tumor presents with visual deterioration. Malignancy may occur |arimariIy, or a preexisting low-grade glioma may become malignant following factors such as radiation ther-
A 6-year-old girl presented with visual deteriora- tion for about two months. Radiological evalua- tion revealed an intra, para and sufiirasellar lesion. The patient was operated on through a right fiiteri- ona/ craniotomy and a subtotal tumor resection performed. The histo[:iathoIogic diagnosis was malignant glioma of the ofiitic chiasma.
Although considered to be a pathology of adults, malign optic glioma may occur in childhood. Presentation may occur with visual deterioration or endocrinological abnormality. Thera[:ieutic intervention is similar to that of the management combination for a malignant glial tumor of the cerebral cortex and optic glioma.
