A member asked:
Please tell me what will a 4 mm cyst in the right frontal lobe cause?
A doctor has provided 1 answer
Likely no much: Sounds like a congenital arachnoid cyst was revealed on imaging. This may be totally asymptomatic but of value to periodically recheck to assure not increasing in size. However, cysts can be secondary to other mechanisms, such a parasitic infections, but typically there would be multiple lesions. Discuss with your doctor.
