What is the ultrasound technique used to assess for this diagnosis, and what is the aim of this technique?
Graded compression. It aims to displace gas containing bowel out of the way to allow visualisation of the incompressible inflamed appendix.
Coronal and axial images demonstrate the appendix (blue dotted line) to be located to lateral to the caecum (green dotted line) with extensive surrounding fat stranding. At the neck of the appendix is a calcific density consistent with an appendicolith (orange arrow).
