Typically, MRI scan results are symmetrical lesions in the mammillary bodies, thalami, tectal plate, and periaqueductal area which showed increased T2 signal in these sites.[5] In our case, brain computed tomography scan result was unremarkable.
Marked flattening of the tectal plate was noted due to cerebral aqueductal dilatation and dilated perimesencephalic cisterns.
Images at the level of the midbrain and pons showed an increased signal of the tectal plate. On the sagittal T2-weighted image with FLAIR, an increased signal was noted in the parietal cortex in the post-central gyrus and fornix, mamillary bodies and peri-aqueductal region.
This is because it is a slow-growing, non-aggressive kind called Tectal Plate Glioma.
In the majority of cases, aqueductal stenosis was caused by a mechanical obstruction within the aqueductal lumen such as membranes or by an extrinsic compression such as a tumor in the tectal plate or the pineal gland (16).
Fortunately Jonny's tumour is a slow-growing, non-aggressive kind called Tectal Plate Glioma.
"I just said, 'can I take his tumour from him?'" Fortunately Jonny's tumour - diagnosed last May - is a slow-growing, non-aggressive kind called Tectal Plate Glioma.
