A focal lesion is an infection, tumor, or injury that develops at a restricted or circumscribed area of tissue.Choroid plexus is bunch of blood vessels present in brain .The calcification means when some calcium deposits get deposited at abnormal space in body like inside a vessel or organ.Posterior fossa artifact means that there is seen a shadow in posterior fossa imaging of brain which is not a pathology but due to some other object outside the human body .
