Hello doctor,I have done a CT scan of the brain recently and found everything was normal but with mega cisterna. The report shows scalp hematoma but that was from childhood and operated. I am worried about mega cisterna. Please suggest.
Hello, Welcome to Chat Doctor forum. I have gone through the reports (attachment removed to protect patient identity). Your CT scan is normal. Mega cisterna magna is a normal variant. So do not worry about that. Scalp hematoma is a collection of blood outside your skull (bone) and is, therefore nothing to worry about. It cannot be due to very old injury as it usually gets absorbed or calcified. It may have resulted from a minor trauma that you may have forgotten. For more information consult a neuro surgeon online
