<s>[INST] I was found to have a 4mm cerebral aneurism at the base of the skull . I had a ct angiongram & waiting for the results to be  confirmed as this was found after my husband found me passed out of the floor. I don't remember the ambulance ride, & was unconcious for 48 hrs. I did have a spider bite that made my legs burn and swell. High temp nausau . [/INST] Hi,Thank you for posting your query.I have noted your symptoms and findings of CT angiogram.You most likely had a syncope or seizure, resulting in transient loss of consciousness.Aneurysm can be confirmed by doing a four vessel angiogram.There are two methods to treat it- either by surgery (clipping) or by endovascular procedure (coiling). The choice between the two can be made after the angiogram.A so now, you should be on anti-seizure medications to prevent the recurrence of seizures.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>
