So, I've just been diagnosed with an area of hyperintensity on both a CT and a MRI that is most likely a 5mm colloid cyst, with no hydrocephalus.. The problem is that I most likely have a cold right now, with sinus pressure, so I'm having a nasty time telling whether I have symptoms from the cyst or not. I see a neurologist tomorrow, but in the meantime:

1. Am I correct that 5mm is relatively small cyst, and fairly unlikely to be causing symptoms?

2. There seems to be sort of a conflict in the literature I can see on the internet between articles that promote a wait and see approach for small asymptomatic cysts and patients/doctors that advocate removing all cysts immediately.
