<s>[INST] I had a CT scan and the findings state: Mild decreased attenuation in the right posterior periventriicular deep white matter. Post craniotomy changes of the midline occipital region noted. May be related to underlying demyelinating process/multiple sclerosis. [/INST] Hi,Thank you for posting your query.I have noted the CT scan findings. They are non-specific and can be seen in a variety of conditions such as ischemia (lack of blood flow to brain) and multiple sclerosis.We need to correlate the CT scan findings with your symptoms. Please get back with your current symptoms, and also why was surgery done.If needed, an MRI of brain may be required to confirm the diagnosis.I hope my answer helps. Please get back if you have any follow up queries or if you require any additional information.Wishing you good health,Dr Sudhir Kumar MD (Internal Medicine), DM (Neurology)Senior Consultant NeurologistApollo Hospitals, Hyderabad, IndiaClick on this link to ask me a DIRECT QUERY:  BLOG: </s>
