Had a headache and nausea with vomiting. Got a CT scan and they said it might be an arachnoid cyst. I never get headaches/nausea. What should I do?

However, depending on their size and location, they could potentially cause symptoms due to mass effect on adjacent structures. Based on limited info, can't tell whether yours is an incidental finding or has any clinical significance. ...Read more

I did a brain CT & it showed a frontal CSF hygromas & frontal arachnoid cyst.  How serious are these findings I'm suffering from confusion, headaches ?

Hygromas: Hygromas associated with confusion and headaches are usually caused by metabolic or toxic problems in the body. Trauma is less likely. Once the problem is corrected then the hygromas resolve spontaneously. Surgery to drain the hygromas is rare unless there is associated subdural bleeding due to a fall from the confusion or encephalopathy. Discuss these findings with a neurosurgeon. ...Read more
