Presentation
Vomiting and developed convulsions in ER
Patient Data
Markedly dilated third and lateral ventricles up to the level of aqueduct of Sylvius.
Bulky tectal plate which suggests an underlying obstructive lesion.
Neurosurgeon informed immediately about the findings for urgent intervention.
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.
Case Discussion
Features are highly suggestive of tectal plate glioma.
