Can an arachnoid cyst cause seizures?

Arachnoid cyst w/mass effect on right aspect of medulla in posterior cranial fossa measuring 15x13mm. What probs might it cause if any? Treat or watch?

Arachnoid cysts: Arachnoid cysts rarely cause problems. Posterior fossa arachnoid cysts may have headaches and vertigo ascribed to them but it is likely that other problems such as arthritis in the neck or inner ear pathology are the actual cause. Most arachnoid cysts are observed. Creating windows in the cysts to drain to other cerebrospinal fluid pathways or placing a shunt is performed for symptomatic cysts. ...Read more

Heard the term arachnoid cyst- info please.?

Spinal fluid balloon: Arachnoid is a membrane in the nervous system which is in contact with spinal fluid. Sometimes the fluid is entrapped in folds of the arachnoid causing a pocket of fluid to form either in skull or spinal canal. At times the cyst can enlarge causing brain or spinal cord compression. Arachnoid cysts can be present at birth or develop later. ...Read more
