Pineal region mass
Updates to Article Attributes
Body
was changed:
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 which may cause a defect in up-gaze (Parinaud syndrome) or, obstructive hydrocephalus if the cerebral aqueduct is compressed.
Differential diagnosis
- pineal parenchymal tumours
-
germ cell tumours
- pineal germinoma (most common; ~ 50% of all tumours)
- pineal embryonal carcinoma
- pineal choriocarcinoma
- pineal yolk sac carcinoma
- endodermal: endodermal sinus tumour - pineal teratoma
- astrocytoma of pineal gland
- pineal metastasis
- pineal cyst
- meningioma near pineal region
- other rare entities
- cavernoma in pineal region
- aneurysm in pineal region
If invasive then a tectal plate mass may be difficult to distinguish from a pineal mass.
