Hi i wonder if you could give me some advice on what i should do. About 5 years back i had an mir scan and it showed a left paracentral arachnoid cyst of CSF intensity on all sequences measuring 22.4 x 26.3 x 34.9 mm located posterior to the cerebellum with a small left lateral extention over the left cerebellar convexity. Axial and sagittal sections through the vertex level likewise reeveal a small 19.1 x 17.9 x 14.6 extra axial fluid lesion over the left superior fronto parietral parasagittal convexity region with subsequent depression of underlying cortex. now im suffering from dizzyness,memory problems and confusion,slow thought processing could this be due to the cyst as many people say that im showing signs of depression.i have had another mir scan but my G.P has said it dose not give the dimensions. i just dont know what to do. thankyou for your time and hope for your reply
