I Had A CT Of My Head And Neck Following

I had a CT of my head and neck following a rear end coll. 11/3/15 it shows a arachnid cyst along the posterior medial right cerebellar hemisphere. 3 x 1.8 x 2 cm. I had a follow up CT 1/12/16 different facilities and Drs. his finding are small cyst posterior to the cerebellum just to the right midline 1.7 cm and may reflect a small arachnoid cyst. & probable mild chronic ischemic change of the cerebral white matter otherwise unremarkable ct scan of the head. I was an emt for 12 years and these docs are not telling me anything. The cerebellum is an important area of the brain!
