Ask a Neurologist and Get an Answer ASAP
Hi Phil. There does appear to be 5mm cyst arising from or near the pineal gland. If the radiologist did not mention it in the report, he or she may have considered it an incidental finding. As the only reading that matters is the radiologist's (or neuroradiologist's) after carefully scrolling through all of the images, I would suggest you have him look at the images again and comment directly on this issue. As an alternative, you can request an R2 (second reading) from another radiologist. That said, pineal cysts are fairly common (seen in 20-30% of individuals at autopsy) and typically benign. As this one does not appear to be causing any mass effect on adjacent tissues, it is very unlikely to be the source of your symptoms.
