Re: US what i see is a longitudinal structure with a lumen and one end is blind...so i guess v r looking at an appendix. the lumen is fluid filled and is not collapsing inspite of pressure ( i can say that from the slight indentation of the mid-portion of the appendix ). the wall also seems thickened and in color doppler mode, i can see some blood vessels. Although, i can't say whether it is increased as would be the case in acute appendicitis.....i will still like to go with that diagnosis. Diagnosis - Acute Appendicitis
