Appendiceal location analysis and review of the misdiagnosis rate of appendicitis associated with deep pelvic cecum on multidetector computed tomography.
OBJECTIVE
To investigate appendiceal location and misdiagnosis rate of appendicitis associated with deep pelvic cecum on multidetector computed tomography (MDCT).


METHODS
Among 1107 appendicitis cases, 25 patients with deep pelvic cecum and 75 patients with conventional cecum on MDCT were retrospectively selected for analysis of appendiceal locations and preoperative misdiagnosis rate.


RESULTS
The major appendiceal direction in deep pelvic cecum group was ascending (84.0%). The misdiagnosis rates of appendicitis in deep pelvic and conventional cecum groups were 16% and 5.3%.


CONCLUSIONS
A deep pelvic cecum may cause misdiagnosis of appendicitis. The appendix associated with deep pelvic cecum mainly demonstrates right ascending direction.
