I was diagnosed with a cyst in my brain, near my pituitary gland, Does anyone know anything about pineal mass?

Question

Like a site to look it up on for the questions that I have while waiting to get to the doc for it, I'd like to ask pertainent questions about this
"condition"...
any help would be appreciated, Thank you

Answer 1

Columbia University has a page about pineal tumours:
http://www.cumc.columbia.edu/dept/nsg/NSGCPMC/specialties/pineal.html

You write that you have a cyst and the page mentioned above writes also about cysts: benign pineal cysts are fairly common and can be an incidental finding. They are often asymptomatic and can be followed, but surgery can be considered if there are symptoms.

However, there are also other pineal masses that can be cystic.

Another good page with plenty of information on pineal region tumours for patients can be found at http://www.cancerbackup.org.uk/Cancertype/Brain/Typesofbraintumour/Pinealregiontumours

Emedicine has also a very comprehensive page about pineal tumours, but it's directed to professionals:
http://www.emedicine.com/med/topic2911.htm

I'm 27 and a 5 year survivor of pineocytoma, a "friendly cancer" of the pineal gland. I had an operation to have it removed and then yet received 6 weeks of radiation therapy, because the tumour reached the border of the removed specimen. I've had MRI check-ups at regular intervals and so far I'm in remission. :)
My initial symptom was double vision, a pressure effect caused by the tumour. The tumour was luckily small and thus better operale.

Good luck to you! If you want to know more about my personal experience, just mail me. :)

Cyst On Pituitary Gland

Answer 3

To start, I would like to tell you that you aren't alone. Lots of people worldwide have had what you refer to as a "pineal mass."
What you have is actually, and don't panic when I tell you this... a brain tumor. There are two kinds of tumor that can affect this area of the brain, one is known as a pineocytoma. It is a slow growing type of brain tumor that occurs in or around the pineal gland... like you said, right near the pituitary gland. There is another type of tumor that can grow in this region which is called a pineoblastoma. This is a similar type of condition which grows much faster than the previous. Unfortunately the pineal region is very difficult to reach, and these tumors often cannot be removed. Depending on its cause, radiation therapy might be an option for treatment, as well as chemotherapy should the mass be malignant in nature. I would suggest reading the following article on webmd. http://www.webmd.com/content/article/5/1680_50617.htm

I wish you all the best.

Answer 4

I have a cyst on my pineal gland that developed after my first several months of chemo therapy. its stayed the same size for ever 4 years andhasnt caused any problems. both my radiologist and oncologist said it pretty common and rarely malignant

No it is not in your mouth. it is on your brain. On the pineal gland. The pineal gland produces melatonin, and regulates your sleep system. However, if there is a tumor there, it can effect your vision.....

Answer 7

Masses in the pineal region fall into three or four categories: pineal parenchymal cysts, germ cell tumors (e.g., seminoma), metastases, and other cystic lesions. The morphology of this dependent lesion suggests a solid, enhancing lesion with areas of subacute hemorrhage. It does not have the appearance of a purely cystic lesion.

Diagnosis
Pineal cyst (benign pseudocyst)

Discussion
Pathology Discussion:
The gross specimen was approximately 2 cm. The unilobular lesion had smooth walls and contained a small amount of brownish fluid. Microscopy of the wall of this pseudocyst demonstrates an inner layer of gliotic brain and outer layer of pineal tissue. Inside, hemosiderin deposition is evident. Higher magnification shows the residual pineal parenchyma. CD-68 stain reveals macrophages within the pseudocyst (along with the hemosiderin). SMI-31 stain highlights the expected pattern of phosphorylates and neurofilaments within the residual pineal parenchyma.

The apparent enhancement of the upper section of the mass on MRI is likely an artifact of windowing. This is an extremely rare presentation of pseudocyst.

Radiology Discussion:

The clinical presentation of a pineal lesion may include obstructive hydrocephalus, Parinaud’s syndrome (characterized by palsy of upward gaze, dissociation of light and accommodation, and failure of convergence) caused by compression of the tectum, and endocrine abnormalities (e.g., precocious puberty) in cases of germ cell tumors. One of the radiologist’s main roles is to determine the origin of the lesion. Lesions arising from adjacent regions and extending to the pineal region include CNS lipoma, epidermoid, arachnoid cyst, astrocytoma, and meningioma. Lesions arising from the pineal gland itself include germ cell tumors, pineal parenchymal lesions, pineal cysts, vascular malformations, and metastases.

Germinoma and teratoma are two germ cell tumors that can arise from the pineal gland. Germinoma is the most common pineal tumor, accounting for 40-50% of all pineal region tumors and two-thirds of all germ cell tumors. It affects primarily children or young adults and is significantly more common in males. Germinomas have a homogenous appearance on MRI and enhance strongly following contrast administration. Teratoma accounts for 15% of pineal masses and also demonstrates male predominance. These lesions are heterogeneous with calcifications and mixed CSF, lipid and soft tissue areas. Germ cell tumors tend to engulf primary pineal calcifications.

Pineal parenchymal lesions include pineocytoma and pineobalstoma. Pineocytoma is an enhancing lesion that affects adults. This benign entity is characterized by good demarcation, homogeneity, and slow growth. It is noninvasive. Pineoblastoma generally affects children and occurs with approximately equal incidence in males and females. Common characteristics of this malignancy include local invasion, distant CNS spread, heterogeneity, calcification, and marked enhancement. It is important to obtain images of the spine to look for metastases. Parenchymal tumors will have intrinsic calcifications, producing an exploded appearance of a primary calcification.

A pineal cyst is found in 40% of routine autopsies. This benign entity is generally smooth and rounded and demonstrates signal characteristics associated with fluid. High protein content or hemorrhage into the cyst, however, may mask simple fluid characteristics.
