Normal appendix on CT


CT appearance of the normal appendix in adults
Stefania Tamburrini, Arturo Brunetti, Michèle Brown, Claude B. Sirlin and Giovanna Casola

The appendix was visualized in 305/372 patients. Its location relative to the cecum was highly variable. The diameter range was 3–10 mm; in 42% of cases the diameter was greater than 6 mm. When the intraluminal content (185/305) was visualized, the diameter was slightly superior to the mean (p=0.0156). In 329 CT scans in which oral contrast material was given, the appendix was filled by contrast material in 74/329 patients. The appendix wall thickness was measurable in 22/305 patients (average 0.15 cm).
There is significant overlap between the normal and abnormal CT appearance of the appendix. Consequently the diagnosis of acute appendicitis should be based not only on the appearance of the appendix but also on the presence of secondary signs.

Thanks ! That is really useful.
So 6.0 mm is not the upper limit, as they say in USG.

exactly just by looking at the diameter you cannot for sure say its appendicitis,clinical picture is very important..
