Should i be concerned with a left choroid fissure neuroepthial cyst. also present left side numbness, weakness in face, arms, legs, cognitive issue?

No: These cysts are benign and are incidental findings. See a neurologist to determine the true cause of your symptoms. If you suffer from headaches that is most likely cause of your symptoms. However still it is best to have neurological consultation.

Yes: Every one of those symptoms is concerns me and needs to be checked out by a neurologist.
