Hi, welcome to our site. I am Dr Saumya Mittal, MD.
Read your query. That is a very significant question and i appreciate your problem. I will try my best to answer your query
There is a possibility that the scan was insignificant. Usually the night hawk, a computerized device, reads the scan and suggests the diagnosis. This may be well inaccurate. The second scan must have been scheduled and read by a radioogist. So I would trust the second scan more.
However if you are still uncomfortable, I would suggest testing an
MRI brain
I hope this helps you. Inform the reports mentioned above/if any other so I can be of help further.
I have given you the answer to the maximum considering the information provided. The results of the tests could further enhance my answer to you.
Please do understand that some details could be extracted from a detailed history and examination.
Please feel free to ask another query. I would be glad to help you. Looking forward to your return query with the details asked so that I can help you further.
(If the answer has helped you, please indicate this)
Best of luck.
