Appendicitis is inflammation of the vermiform appendix. It is a very common condition in general radiology practice and is one of the main reasons for abdominal surgery in young patients.
CT is the most sensitive modality to detect appendicitis. Acute appendicitis is typically a disease apendicutis children and young adults with a peak incidence in the 2 nd to 3 rd decades of life 1.
This progression is only seen in a minority of cases and is unhelpful in children who often present with vague and non-specific signs and symptoms. It also relies on the appendix being in a ‘normal’ position, which is not the case in a significant number of cases see below.
The Alvarado score is a clinical score that can be useful to help risk stratify.
Appendicitis is typically caused by obstruction of the appendiceal lumen, with the resultant build-up of fluid, secondary infection, venous congestion, ischemia and necrosis. Obstruction may be caused by One of the biggest challenges of imaging the appendix is finding it. Once confidently identified, assessing its normality is relatively straightforward.
The location of the base of the appendix is relatively constant, located roughly between the ileocecal valve and the apex of the cecum.
This apendicits is maintained even when the cecum is mobile. The distribution of positions is described as 7, If an inflammatory phlegmon is present, displacement of caecal gas with mural thickening may be evident.
Ultrasound with its lack of ionising radiation should be the investigation of choice in young patients. With a competent user, ultrasonography is reliable at identifying abnormal appendices, especially in thin patients. However, the identification of a normal appendix is more problematic, and in many instances, appendicitis cannot be ruled out.
The technique used is known as graded compression, using the linear probe over the site of maximal thickness, with gradual increasing pressure exerted to displace normal overlying bowel gas. apeneicitis
Confirming that the structure visualized is the appendix is clearly essential and requires demonstration of it being blind-ending and arising from the base of the cecum.
Identifying the terminal ileum confidently is also helpful. A recently described dynamic ultrasound technique using a sequential 3-step patient positioning protocol has been shown to increase the visualization rate of the appendix 9. Slightly larger absolute and relative visualization rates were seen in children. The authors suggested that the effect of the LPO positioning step improved the acoustic window by shifting bowel contents.

The need for contrast IV, oral or both is debatable and varies from institution to institution. Oral contrast has not been shown to increase the sensitivity of CT Retrocecl is recommended as the second line modality for suspected acute appendicitis in pregnancy patients, where available 13, Protocols vary widely, but most include imaging in three planes with a rapidly acquired sequence with T2 weighting, and some include T2 fat-suppressed imaging.
MRI findings mirror those of other modalities, with luminal distension and widening, wall thickening and periappendiceal free fluid. Treatment is appendicectomy, which can be performed either open or laparoscopically 5. Mortality from simple appendicitis is approximately 0. It is in this situation that radiologists have a therapeutic role to play with percutaneous CT- or US-guided drainages. Clinically, the most common differential is that of mesenteric adenitiswhich can be differentiated by the identification of a normal appendix and enlarged mesenteric lymph nodes.
