(Left) Sagittal MPR image
from a CT colonography study
performed for anemia shows

distended appendix
projects into the cecal lumen.
(Right) Endoluminal view from
the prone series of the same
study demonstrates smooth
extrinsic compression into the
cecal lumen.
Diagnoses: Bowel

(Right) Macroscopic cross
section of the resected
specimen shows the typical

Doppler ultrasound of the
right lower quadrant in a
patient who presented with
fullness shows mucocele
containing mixed echogenicity
contents with no internal color
flow. Note the posterior
