Patient Data

Age: 14 years

CT

Markedly dilated third and lateral ventricles up to the level of aqueduct of Sylvius.

Bulky tectal plate which suggests an underlying obstructive lesion.

MRI

Acute obstructive hydrocephalus ( transependymal edema ) with interval placement of a right transparietal VP shunt catheter, tip in the right posterior horn.

Abnormal FLAIR high signal of the tectal plate with bulky appearance on sagittal T1W but no restriction on DWI or enhancement on post-contrast sequences.

Features are highly suggestive of tectal plate glioma.
