Pineal cyst







Findings

A cystic lesion (2.0 x 1.8 x 1.2 cm) with thin and well-defined enhancing walls (Figure 1 and Figure 2) places mild mass-effect on the tectum. No hydrocephalus is present. The cystic lesion (Figure 1, Figure 2, Figure 3 and Figure 4) is homogeneously isointense to CSF on T1-weighted imaging, uniformly hyperintense on FLAIR sequences, and isointense to CSF on T2-weighted imaging. No diffusion restriction is seen on diffusion-weighted imaging. These findings are most compatible with a pineal cyst. Less likely, this may represent a pinecytoma.

Differential diagnosis:
- Pineal cyst
- Normal pineal
- Pineocytoma
- Epidermoid cyst
- Arachnoid cyst
- Germ cell neoplasm


Diagnosis: Pineal cyst


Pineal cysts are usually asymptomatic and are often discovered incidentally. They have been discovered in up to 40% of patients on autopsy studies. Patients with large pineal cysts may experience headaches secondary to obstructive hydrocephalus. Rarely, pineal cysts can produce Parinaud syndrome (paralysis of upward gaze, lid retraction, and abnormal pupillary movements). If the cyst is hemorrhagic, acute hydrocephalus can develop. Young females (aged 21-30) are affected more than males (female to male ratio is 3:1). The cysts commonly enlarge with puberty and then regress with age.

On CT, the pineal cyst contents are usually isodense relative to CSF. The wall may be calcified. The cyst wall (nodular or thin) may enhance with contrast. Pineal cysts have a variable appearance with MR. Cystic contents are most often hyperintense relative to CSF, but may be isointense on T1-weighted imaging. On T2-weighted sequences, the cystic contents are either isointense or hypointense to CSF. On FLAIR sequences, the cystic contents are hyperintense. No restriction is seen with diffusion-weighted imaging. The cyst walls may enhance (60%). On delayed images, the cystic contents may enhance.

The key management issue regarding a pineal cyst, is the fact that they can be indistinguishable from a pinecytoma. Therefore, a histological diagnosis may be needed to make the distinction. If biopsy or surgery is not performed, long-term follow-up imaging should be obtained. Some suggest that clinical follow-up without imaging is an acceptable alternative. In one follow-up series, the cysts did not change in size in 75% of patients.

  1. As a sign of gratitude for how my husband was saved from pineal cyst , i decided to reach out to those still suffering from this.
    My husband was diagnosed of pineal cyst, and it was really tough and heartbreaking for me because he was my all and the symptoms were terrible, he had weakness of the body , and he always complain of ringing in ears (tinnitus) and headache . we tried various therapies prescribed by our neurologist but none could cure him.one faithful day i decided to go for a researched and i saw a testimony by someone who was cured and so many other with similar brain problem, and he left the contact of the doctor who had the cure to pineal cyst. I never imagine pineal cyst has a cure not until i contacted him and he assured me my husband will be fine. I got the herbal medication he recommended and my husband used it and in one months time he was fully okay even up till this moment he is so full of life. pineal cyst has a cure and it is a herbal cure contact the doctor for more info on drwilliams098675@gmail.com on how to get the medication.

  2. "Dear Williams, I wanted to drop you a note and say 'THANK YOU', from the bottom of my heart. I was browsing the Internet back in AUGUST this year looking for help, any help. I have been diagnosed with a pineal cyst of 7. mm that was extremely causing me a vision balance & headaches , painful especially at night before going to bed. Thankfully enough I accidentally came across Mrs shelley thanking dr williams for his medication. I thought I should give his medicine a try and if it worked then the thirty something bucks would have been worth it. I ordered his medicine and went to my local health store and bought the herbs and vitamins and the other more basic ingredients for his medicine and then started his medication that day. After 7 days I didn't see any change so I thought 'here we go again'. But it wasn't another disappointment. By the end of the 4th week on a bright Monday morning, all the pain,headaches and the awful bloated feeling just stopped. I immediately went and performed another scan and guess what? The pineal cyst of 7. mm was not there anymore. I was so happy!

    Thanks to your advice, I now know how to prevent any future pineal cyst formation and the array of symptoms that goes along with it, including the headache unexpected seizure and visual disturbances. Thank you so much for everything!"for more information you can email him on drwilliam098675@gmail.com for advice and for his product.

  3. MY NAME IS NITA,A LIVING CLAIM OF DR WILLIAMS HERBAL MEDICINE.

    Dr Williams,herbal treatment is the best to shrink pineal cyst naturally.

    Four months ago, I was scheduled an operation to remove a fairly large pineal cyst (approx. 8 mm), which had caused me a great deal of headache and tightness around my head. . My doctor insisted that there was no other choice but to go under the knife and I had reluctantly agreed (after trying several medications to decrease the size of the pineal cyst to no avail). It was approx. 2 months prior to the surgery when my husband comes across dr williams herbal remedies which my husband found and ordered for me online. With the help of my loving husband, I followed the step and procedure on how i should be taking it. and one months later I was scheduled for an scan check: it was shocking. The pineal cyst had completely gone, I had consulted my doctor and cancelled the surgery and with his dedicated counseling guidance I managed to completely treat the pineal cyst from my pineal gland , along with the pain and anxiety that this condition had inflicted on me. Thank you so much for your kind help DOCTOR,for more information on how to get his medication you can visit his blog on http://pinealcystnaturalcure.blogspot.com
