So, I'm going to go out on a limb here and ask you if you suffer anxiety? I only ask because you have had tons of tests and doctors appointments. :>) Health anxiety is real and can greatly impact our life. And I do have to wonder if you suffer this.
Syncope is not uncommon. And it is not usually much to worry about. Are you well hydrated, for example? Dehydration can cause syncope. Low blood sugar can cause this. Speak to your doctors about this. But your report doesn't sound right to me in general as you don't have 'syncope' as seen on an MRI. It's a symptom. And metastasis on an MRI with nothing else and no evidence of cancer, that's also a strange thing to have on the report
So, on pregnancy tests. Here's the deal. You really have to read them within the time the packaging states. So, that is usually right after and for a short period of time following that. If you let them sit at all beyond that, they no longer are reliable. If you don't see a line immediately, then what you were probably seeing was an evaporation line. If you, otherwise, got lines immediately, that does mean you are likely pregnant. The tests are very accurate. It picks up a hormone you only have if pregnant. but a lot of women get confused because they don't throw the test away after say 10 to 20 minutes and a line develops. You aren't having miscarriages each time over the course of 4 months, right? (you'd likely know). I tried to conceive for a long time. It's a crazy journey and definitely emotional. Hang in there with that!
You should contact the ordering doctor and/or interpreting doctor (radiologist) for clarification. Sometimes the history/indication line on a radiology report lists things your doctor wants to rule out. For example, a chest radiology report at the top might state INDICATION: Pneumonia, meaning the purpose of the study is to rule out pneumonia, but for billing purposes the doctor must list a symptom or diagnosis rather than the words rule out pneumonia. Another possibility is that this is a voice dictation error. Radiologists use voice dictation software (similar to the type you use for your smartphone, but more advanced and with a medical focus). This software is not 100% perfect and may generate words not intended.
