Hello to all. Couple of days ago my Obgyn did physical and was able to feel a mass in the lower part of my belly, both outside and internally. I was sent to US the next day and she called back saying it came back normal. It was a big relief to know this initially. But then she said "she was surprised" to find out they did not see what she was able to touch with her own hands. This is unlikely to disappear for 24 hours. The question is: can a palpable mass be missed on US? Is this possible at all? Thanks & take care.
