Tectal Glioma

7 years old child presents with headaches and vomiting since a few weeks. MRI: transversal T2, FLAIR, sagittal T2 - show poorly delineated tumor in the quadrigeminal plate that has high signal on T2 sequences. There was no contrast enhancement (not shown). This brainstem tumor compromises cerebral aqueduct causing supratentorial obstructive hydrocephalus. Radiologic appearance of this tumor strongly suggest Tectal Glioma. Those are commonly slow growing usually benign tumors that mostly require follow up. However hydrocephalus is of concern and often requires shunting.
