Role of Abdominal X-ray in Appendicitis
The aetiology of Appendicitis is usually related to luminal obstruction,often by lymphoid hyperplasia or a faecolith.
• The presence of a calcified appendicolith in the RLQ ,combined with
abdominal pain,has ahigh positive predictive value for acute appendicitis.
• Other signs are less specific and include caecal wall thickening,small-bowel ileus and decreased small-bowel gas in the RIF.
• Free peritoneal fluid can lead to loss of the psoas out line,loss of the fat planes around the bladder and loss of definition of the inferior liver outline.
