Overview

JDMS: Appendicular Lymphoid Hyperplasia in the Differential Diagnosis of Acute Appendicitis: Sonographic Findings is organized by Society of Diagnostic Medical Sonography (SDMS).

Start Date: 12/11/2019
Expiration Date: 12/11/2022

Accreditation:
This Course has been approved for a maximum of 0.5 Credits

Objectives: 
To describe sonographic findings of appendicular lymphoid hyperplasia (ALH) and to report demographic data of patients with ALH operated for acute appendicitis (AA).

Materials and Methods: 
In a retrospective study, 694 biopsies of consecutive AA surgeries with previous ultrasonography (US) were reviewed, after selecting the ALH cases.

Results: 
Twenty-five ALH cases were proved histologically (3.8% of appendectomies). The mean age was 13 years, with 84% under 20 years. US findings showed increased appendiceal diameter (average 7 mm) (82%), hypoechogenic pseudonodular mucosal thickening (50%), concentric parietal thickening (13%), and periappendiceal inflammatory changes (18%). In four cases, a normal appendix was noted on US, with two associated with intestinal intussusceptions.

Conclusion: 
ALH is a benign entity most frequent in children that can predispose to AA. Both pathologies can increase the appendiceal diameter. In the pediatric group, ALH could be considered when hypoechogenic pseudonodular appendicular mucosal thickening in the absence of periappendiceal inflammatory changes occurs.

Additional details will be posted as soon as information is available.
