Objectives: After studying the article entitled “Appendicular Lymphoid Hyperplasia in the Differential Diagnosis of Acute Appendicitis: Sonographic Findings,” you will be able to:
Describe the sonographic appearance of appendicular lymphoid hyperplasia (ALH)
Describe the age group most commonly affected by ALH
Differentiate between acute appendicitis and ALH
Which of the following statements is true regarding ALH? ALH is a benign condition ALH is a surgical emergency ALH is almost always due to an obstruction of the appendicular lumen Appendicular lymphoid hyperplasia may progress to peritonitis
The age group that ALH most affects is: Adults Elderly Infants Pediatric
The following are sonographic features of ALH except: Absence of periappendiceal inflammatory changes Hypoechoic appendicular mucosal thickening Obstructing fecolith Pseudonodular appendicular mucosa
Which of the following sonographic findings is not associated with acute appendicitis? Hyperemia with color Doppler Hypoechoic pseudonodular mucosal thickening Increased appendicular diameter greater than 7 mm Periappendiceal inflammatory changes
In this study that included 761 appendectomies, how many had a histological diagnosis of ALH? 1.5% 3.8% 12.9% 50%
