Acute appendicitis is also one of the most common abdominal emergencies worldwide in urgent care and primary care settings. The clinical presentation can vary widely from classical to chronic. Diagnosis in children can be elusive because children can present with typical and atypical symptoms. Obtaining a confident preoperative diagnosis is still a challenge since the possibility of appendicitis must be entertained in any child presenting with an acute abdomen before perforation occurs. The Alvarado and Pediatric Scoring system will help narrow down a differential diagnosis but a decision has to be made on which imaging modality will confirm the diagnosis. Ultrasound (US) and Computed Tomography (CT) are the two most utilized. CT has a higher sensitivity over US, It is suggested that US be utilized first as it can be quicker even though it has a lower sensitivity compared to CT especially if ionizing radiation of concern.
