Patient's Query
Hi doctor,
My CT scan came back, and it said the following: Everything looks fine, but there is a retrocerebellar cyst or prominent cisterna. My symptoms include having experienced vertigo 5 months ago, feeling slightly lightheaded and off-balance at present, getting dizzy when I lift weights, and experiencing neck pain. Laboratory tests that have been completed include blood work, a CT scan, and an MRI for the brain, all done 5 months ago. The next scheduled tests are a neck and spinal MRI, which will take place next week. I need your help.
Hi,
I am glad you chose icliniq for your medical-related queries.
I understand your concern.
Good day, and thank you for the information. First, I would like to ask if your dizziness is a spinning or rotating type. If it is, it could be vertigo, which is characterized by a spinning sensation. Vertigo can either be central, related to the cerebellum and its connections, or peripheral, related to the ear. The best imaging test to check for cerebellum issues is an MRI (magnetic resonance imaging). A cisterna magna is fine as long as it does not compress other structures. I have not seen the images, but based on the official results, the structures appear to be okay. There is no tumor or stroke. Additional workup would involve checking for vessel patency in the brain circulation through angiography studies. You should also get yourself checked by an ENT (ear, nose, and throat) specialist or visit the hearing and balance unit. However, if your dizziness is not the spinning or rotatory type, if you feel like fainting, light-headedness, or experience near-blackouts or syncope, you should have yourself cleared by a cardiologist, especially if it occurs while lifting weights. Be sure to stay hydrated as well. In the meantime, please avoid lifting heavy weights while waiting for the results of the spine MRI.
You can always come back and reach me at icliniq.com.
Thank you for consulting me.
Patient's Query
Hi doctor,
Thank you again for your time; I greatly appreciate it.
My vertigo went away. However, I just want to know what does retrocerebellar cyst or prominent cisterna mean? Is that something to be concerned about? What should I do? My vertigo has subsided, but I occasionally feel lightheaded, although it is not the spinning type. I drive a lot for work, and this sensation usually occurs after extended periods of driving or when I am on the phone for too long. I am curious about the cyst and the cisterna. Have you seen the CT scan and MRI report? What do you recommend?
Hi,
Glad to have you back!
I am here to help you get the best medical advice.
I understand your concern.
A prominent cistern or cisterna magna as an incidental finding is okay. No operations are needed. It may be a normal variant because you have no symptoms. It can be seen in other normal individuals as well. The retrocerebellar cistern is a normal space for the fluid in the brain. When they say 'cyst,' it may refer to a pocket of fluid. Based on your profile and results, it is a prominent cistern, not a cyst. The recommendation is to observe and relax.
I hope this has helped you.
Thank you.
