Pdf Summary

The study guide for the RadioGraphics Online SA-CME Test 210162 focuses on the imaging spectrum of non-Hodgkin lymphoma (NHL) in children, adolescents, and young adults. Key points addressed in the guide include the most common histologic subtypes of pediatric NHL and features that aid in differentiating NHL from other conditions such as Crohn's disease. The guide discusses optimal imaging techniques and appearances of NHL in various organs, along with considerations for specific patient scenarios.<br /><br />1. The most common histologic subtype of pediatric NHL is Burkitt and Burkitt-like lymphomas.<br /><br />2. Differentiating Crohn's disease from NHL can be aided by the presence of "loss of bowel wall stratification" as shown in the guide's illustrations.<br /><br />3. In cases of splenic lymphoma, "late arterial and early venous" contrast phases are optimal for detecting small lymphomatous infiltrates using a CT scan.<br /><br />4. The typical imaging appearance of renal NHL at ultrasound (US) is "multiple hypoechoic masses that are frequently bilateral."<br /><br />5. For a 4-year-old boy with intussusception, a radiologist should suspect the "presence of a pathologic lead point," especially given the presentation of an acute abdomen.<br /><br />This guide aims to aid radiologists in understanding the imaging characteristics of NHL in young patients and applying that knowledge to clinical practice. However, it notes that to earn SA-CME credit, professionals must take an online test at the RSNA learning center, as credit is not awarded for study of this document alone.
