Hello, Thanks for the query, Hello, Thanks for the query. Before I respond to your question, let me tell you that the causes of headache are many and this can be due to sinusitis, migraine, tension headache, cluster headache, brain tumor/infection, problem in the blood vessels and so on. Further, the presence of associated complaints like vomiting, nausea, any proceeding signs before headache and weakness of legs/hands etc will help us clarify the diagnosis. With the limited information, I feel that you may be having sinusitis as a cause of headache. Please note that the interpretation of imaging findings should always be done in a given clinical context. The presence of prominent right ventricle in your case could be a normal variant also. It can be seen in people with decreased brain volume in that side. If you have any concern, please take a second oipinion with another local neurologist who will help you after a clinical evaluation. Hope this clarifies Best wishes
