Are pineal tumors cancerous?

Grade II or III pineal parenchymal or papillary tumors of the pineal region are both mid-grade tumors. This means the tumors have a higher chance of coming back after being removed. Grade IV pineoblastoma are malignant (cancerous). This means they are fast-growing tumors that tend to invade nearby tissue.

Is pineoblastoma curable?

Pineoblastoma can be very difficult to treat. It can spread within the brain and the fluid (cerebrospinal fluid) around the brain, but it rarely spreads beyond the central nervous system. Treatment usually involves surgery to remove as much of the cancer as possible.

What is the difference between a pineal cyst and tumor?

Pineal cysts Dermoid and epidermoid cysts are slow-growing sacs filled with material; they are not true tumors because they do not arise from brain tissue. Similar to germ cell tumors, these cysts are the result of cells being trapped in the brain during embryonic development.

How is a pineal tumor removed?

As with many other brain tumors, pineal region tumors are best treated with surgery. The surgery, called resection, removes all or part of the tumor — the more tumor that’s removed the better the prognosis for recovery. These surgical procedures are highly involved and can take several hours.

Are pineal cysts life threatening?

These cysts are benign, which means not malignant or cancerous. Sometimes an MRI of the pineal cyst needs to be repeated with an intravenous contrast (dye) to rule out a pineal tumor. The cyst is rarely symptomatic; however, when symptoms do occur, they are difficult to attribute specifically to the pineal cyst.

When should a pineal cyst be removed?

If the symptoms are interfering with a patient’s quality of life and all other causes have been ruled out, Patel recommends surgery to remove the suspected pineal lesion. Patel, who is one of only a handful of surgeons in the world who resects pineal cysts, has now performed more than 40 of these surgeries.
