Tectal pilocytic astrocytoma
We found out this past June 2017 that our son, 19 yrs. old, (because of double vision in his left eye peripheral when he looks right), has a non-enhancing lobulated lesion (measures 1.1 x 1.2 x 1.4 cm) involving the right inferior aspect of the tectal plate extending into the superior aspect of the fourth ventricle; relatively unchanged from both a September & December 2017 MRI’s. Doctor states that primary differential remains as stable low-grade glioma and centered in the right inferior colliculus of the tectal plate and surrounding the cerebral aqueduct redemonstrated; relatively unchanged in size and imaging characteristics in comparison to prior studies. Inferiorly it is extending into the superior aspect of the fourth ventricle. His next MRI is in May of this year. This is a wait and see prognosis.
