Benign pineal gland cyst cause?

Cyst (Definition)

A cyst is a structure or mass that consists of a cellular lined sac. It is typically filled with fluid but may be filled with solid material. It can be congenital, traumatic, or acquired. They may develop nearly anywhere in the body and usually require complete excision for eradication or they are likely to recur. Fluid filled sacs that are not cellular lined ...Read more

Can a 1.5x1.2 cm pineal cyst (with multiple symptoms) ever be considered an emergency situation?  

Ever's a strong word: Something like that's almost NEVER an emergency since the size's not THAT HUGE to displace vital structures in the area. But, it can clearly be annoying & if jutting out in just the right way squish things that'll make you take notice. Kinda' like sittin' on a THICK WALLET (George Costanza style).

What to do if I have resently been diagnosed with a binine pineal gland cyst and I was wondering what the risk are of it growing?

Experience: In my practice small cysts of the pineal are far from rare, and often we follow these for a while with yearly MRI films. Most never increase in size, and some even shrink over time, and it is rare that the typical cyst will expand to the point of requiring surgery. ...Read more

What are the symptoms of a pineal cyst?

These vary: Pineal cysts are fluid collections surrounded by a membrane located near the pineal gland. Most often these are found incidentally on ct/mri scans done for other reasons. If these cysts become very large they can lead to obstruction of the normal spinal fluid pathways. This can lead to symptoms of headache, nausea, blurred vision- ie. Symptoms of hydrocephalus. ...Read more

How do you tell the difference between a pineal tumor and a pineal cyst?

How do you tell the difference between a pineal tumor and a pineal cyst?

A biopsy or imaging: True pineal gland cysts are not brain tumors; rather, they are a completely benign cysts. The large majority of pineal gland cysts do not enlarge much if at all. However, some do enlarge over time slowly. Even though pineal cysts are benign and usually harmless, they can mimic a tumor, they often need to be distinguished from other cystic tumors via biopsies or imaging study (ie MRI of the brain). ...Read more

17mm pineal cyst found on MRI, going to be discussed in MDT meeting. How worried should I be?

Depends on symptoms: Kayleigh,
Pineal cysts are generally benign and seen quite frequently in folks who have nothing wrong with their brain. Once they get above 5 mm, they have the possibility of causing symptoms such as headache, seizure, or light sensitivity. Nowadays if too large, they are drained through endoscopic brain surgery which requires only one night hospital stay and is relatively painless. ...Read more

Pineal cyst of 0.7x1.0 x1.0 CM abut to tectal plate does this mean its causing damage? What does it mean to be multilocular?

Pineal cyst of 0.7x1.0 x1.0 CM abut to tectal plate does this mean its causing damage? What does it mean to be multilocular?

Pineal cyst: It sounds like you're reading from a radiological report, which describes the cyst's locale (abutting the tectal plate, a part of the skull). "abut" means to be next to, or to have a common boundary with. It does not mean damage. "multilocular" means the cyst has multiple pouches rather than only one. Please discuss these findings with your own doctor so that s/he can address your concerns. ...Read more

HI Dr. What is the difference between a simple Pineal cyst and a complex Pineal Cyst. Looks like my MRI showed a 1.3 CM Complex Pineal Cyst. Thank you?

HI Dr. What is the difference between a simple Pineal cyst and a complex Pineal Cyst. Looks like my MRI showed a 1.3 CM Complex Pineal Cyst. Thank you?

Liquid vs other stuf: A simple cyst generally contains only fluid. A complex cyst is a sac that contains mostly fluid (liquid) but also some material - cells / tissue or colloid or something solid - inside. That solid material makes its appearance different than just a fluid-filled sac. Larger (> 1cm) cysts in the pineal gland can't be distinguished from cystic tumors & so repeated scans are generally the rule. TTYD. ...Read more

I have a calcified 11mm pineal cyst after weeks of headaches & a seizuree. Symptoms continuing w/ insomnia Do cysts these size (>5 mm) often shrink?

Ask a neurosurgeon: Your best bet is to consult with a neurosurgeon. Most pineal cysts are benign and slow growing, but they need to be distinguished from a tumor. They could also grow to compress the cerebral aqueduct which could disrupt the normal flow of cerebrospinal fluid and cause build up of fluid in your brain. It could also compress the brain stem interfering with your visual gaze. ...Read more

My neurologist said I have a 7mm pineal cyst & I have migraines. He didn't quite explain well & I would like to know more about it. Any info helps.?

Likely unrelated: Migraines are very common in 23 year old women like yourself. They usually are caused by genes, hormones, and triggers and not by cysts or anything else that can be found on an MRI. Pineal cysts, when found on MRIs, are usually just a "birthmark" and usually don't cause any problems. At that size I wouldn't expect your pineal cyst to cause any problems. I hope that helps! ...Read more

I had an MRI of my brain and a pineal cyst measuring 4 by 8 by 4 mm was found, which did not show up on MRI I had 18 months ago. Cause for concern?

No concern: These pineal cysts are often found incidentally. When they are that small they cause no symptoms. I suspect that it was there previously but technique was such that it wasn't seen. ...Read more

Here we go again: Presumably you didn't just wander into an MRI facility & made an impulse purchase. Your doctor ordered the MRIs, & for a reason. The MRIs aren't the pt; you are. The doc who ordered the MRIs & knows YOU AS A WHOLE PERSON is ethically obligated to interpret the significance of the MRIs; or if (s)he can't, to find someone who can. You have a right to an explanation in terms you can understand. ...Read more

How dangerous is a 1.5cm pineal cyst, no hydrocephalus but I have headaches, nausea, tingling and anxiety.

How dangerous is a 1.5cm pineal cyst, no hydrocephalus but I have headaches, nausea, tingling and anxiety.

Worthy of removal: It is not life-threatening, but the symptoms can worsen and affect important vision functions. Pain can increase and since the surgery is considered the safest of all brain surgeries w/ nearly zero mortality, it's a good idea. Recovery may take awhile but is almost guaranteed. Talk about all of this w/ neurologist - I'll connect you to one here - Dr. Dariush Saghafi. Best! ...Read more

MRI found 17mm pineal cyst, have headaches, nausea, tingling. Neuro said repeat scan in 6 months. Should I be worried?

MRI found 17mm pineal cyst, have headaches, nausea, tingling. Neuro said repeat scan in 6 months. Should I be worried?

Second Opinion: You could get a second opinion, which I guess is what I am on some level! ;-)

If it is just a cyst, then a wait and approach attitude seems fine. There are three things that will happen during the 6 months: 1. It will get bigger 2. It will get smaller 3. It will stay the same size.

You could see a neurosurgeon, but that's moving towards a surgical approach to something that might go away. ...Read more

My 10 year old son was diagnosed with a pineal cyst 3 mys ago. He is having vision, hearing, seizures, and headaches. Why is nuro dr not concerned?

Not sure: Many of the symptoms you describe would not be caused by a pineal cyst. These cysts are typically benign and are watched over time to ensure they don't increase in size. The only symptom that could be related to the pineal cyst would be the vison, but there tends to be very specific vision changes related to pineal enlargement. If you're dissatisfied get a 2nd opinion. ...Read more
