Pineal region mass

Masses in the pineal region have a relatively broad differential because of the variety of cell types found in the region. 

If large enough, the mass may compress the tectal plate and may cause a defect in up-gaze (Parinaud syndrome) or obstructive hydrocephalus, if the cerebral aqueduct is compressed.

Differential diagnosis

If invasive, a tectal plate mass may be difficult to distinguish from a pineal mass.
