Patient Data

Age: 2 years

Ultrasound

The right iliac fossa was examined by graded compression ultrasound.

Ileo-cecal lymphadenopathy is also noted.

Case Discussion

Ultrasound is the investigation of choice in young patients being investigated for acute appendicitis.

Graded compression ultrasound is the technique used.

Findings to support the diagnosis are: 

  • aperistaltic, non-compressible, dilated appendix (>6 mm outer diameter)
  • target appearance
  • periappendiceal fluid collection
  • periappendiceal hyperechoic structure
  • echogenic prominent pericaecal fat
  • appendicolith
  • distinct appendiceal wall layers
