A Rare Cause of Hydrocephaly: Tectal Glioma

Abstract

Tectal gliomas are a distinct form of pediatric brainstem tumor usually present with increased intracranial pressure. The tumor may arise from different origins and the most common histologic form is low-grade astrocytoma. We would like to remind and emphasize why it is important to report a tectal glioma in magnetic resonance imaging reports giving two case samples.

A Rare Cause of Hydrocephaly: Tectal Glioma

Öz

Tektal gliomlar pediatrik beyin sapı tümörlerinin ayrı bir grubu olup genellikle kafaiçi basıncı artışı ile ortaya çıkarlar. Tümör farklı kaynaklardan gelişebilir ve en sık histolojik formu düşük evreli astrositomdur. Burada iki olgunun sunumu ile manyetik rezonans görüntülemede tektal gliom raporlamanın önemini hatırlatmak ve vurgulamak istiyoruz
