  1. Samuel Azeze; Case Western Reserve University School of Medicine

Imaging signs have been a staple in teaching radiology residents how to swiftly recognize a diagnosis by associating an anatomic image with an inanimate object. Knowing a wide selection of radiology signs that are inspired by inanimate objects may lead to a quick diagnosis and expedited treatment for often life-threatening conditions.

Educational Goals / Teaching Points
By the end of this presentation the reader should be able to: Recognize several radiographic and CT imaging signs associated and their associated pathologies, understand the pathophysiology involved in creating the radiological appearance, and recognize common treatments for these pathologies

Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
Will have a case based pictorial review of multiple commonly encountered radiology signs. Will first go over multiple "astronomically" inspired signs including: Comet tail sign, galaxy sign, "starry sky" appearance, sunburst sign, and "twinkling" artifact. Next, will proceed to review multiple important food signs including: Berry aneurysm, pancake brain, salt and pepper calvarium, honeycomb lungs, eggshell calcification popcorn calcification, headcheese sign, Oreo cookie sign, coffee bean Sign, apple core lesion, omental caking, nutmeg liver, Pepsi sign, and sausage digit. The next subsection of signs we will cover include those falling under "Household objects." These will include the corkscrew sign, coin sign, telephone receiver deformity, dinner fork deformity, hockey stick sign, napkin ring sign, polka-dot sign, rugger jersey spine, and string of pearls sign. Finally, we will cover multiple "weapon and ammunition inspired signs" including bullet-shaped vertebra, cannonball metastases, saber-sheath trachea, and Scimitar syndrome.

Being familiar with the multiple imaging signs presented in this presentation will allow the viewing radiology residents to swiftly recognize and make a diagnosis by associating an anatomic image with an inanimate object.
