Roentgen Diagnosis of Acute Appendicitis

Gas-filled appendix with meniscus: Outline of the appendicolith

“…Appendicoliths are demonstrated in 22% to 50% of children [16,17] and in up to 10% to 12% of adults [14,18]. Edema of the cecal wall with a long air fluid level on decubitus view [11] and luminal dilation [19] may be identified. The terminal ileum may also demonstrate edema and ileus [2,10,12].…”

The Iliac Streak: a new radiological sign of a perforated appendix in peritonitis

“…The radiological features suggestive of appendicitis have been described before 2,4,5,6 . These include, the presence of radio‐opaque faecoliths, and fluid levels in the right iliac fossa, loss of definition in the right lower quadrant with blurring of the psoas outline, and a lumbar scoliosis to the right as a result of psoas muscle spasm.…”
