thank you for your query. this means that there is a mass of granulation tissue (like old healed scars
) which have calcified (again a sign of completed healing process) in the right priental lobe of the brain (that is a few inches above your right ear, inside the brain), beneath the cortex
(i.e. deeper into the brain tissue) measuring 0.64 * 0.44 cm (which is quite small), without any surrounding oedema or fluid collection (perilesional odema occurs in active, fresh tumor
or bleeding). this probably means some healed scar of an injury
occuring during the accident. IT may also mean some other chronic infective process (chance is less).
i would suggest you consult a neurologist
for the same for further management.
Hope i've been able to satisfy your query. please feel free to contact me for any further clarifications. best of luck.
