I'm unsure of the connection between the brain scan and a nasal polyp. But I don't think having just one polyp can be that rare. When I went into hospital with a bleeding one many years ago, it was just the one I had. Was told I'd get more but haven't yet.
One polyp (unilateral) is not unusual and is almost always not malignant.
However unilateral polyps must always be investigated further (MRI scan) just to exclude the outside possibility of it being malignant OR not a nasal polyp at all.
Hope you and Mrs Sqad have a nice meal after the cardio visit.
Mr Alba and I did a recce yesterday for his hospital visit today and we went to one of the vans selling hotdogs etc for lunch. He does know how to spoil a person ?:
