Pineal tumors develop in the cells of the pineal gland. The pineal gland is involved in the secretion of specific hormones and is located in the center of the brain.
Certain tumor types originating in the pineal region may or may not involve the pineal gland and include:
- Dermoid cysts
- Non-germinoma (teratoma, endodermal sinus tumor, embryonal cell tumor, choriocarcinoma, and mixed tumors)
The three types of pineal tumors are:
- Mixed Pineal Tumor – contains a combination of cell types.
- Pineoblastoma – a more aggressive, grade IV, malignant tumor. A grade III intermediate form has also been described.
- Pineocytoma – a slow-growing, grade II tumor.
The pineal gland is located at the rear of the third ventricle, which is one of the fluid-filled cavities of the brain. The exact cause of pineal cell tumors is unknown. However, chromosomal abnormalities have been identified by scientists, which may play a role in the development of these tumors.
Pineal Tumor Symptoms
Pineal tumor symptoms are often caused by the blockage of cerebrospinal fluid and eye movement pathways problems. Additional symptoms are:
- Memory Disturbances
- Nausea and Vomiting
- Visual Changes
