There exist many kinds of non-pathologic or less significant findings that are commonly misread as rather significant diseases on chest CT scan. The educational goal of this exhibit is to familiarize radiologists to the characteristic CT appearances of non-pathologic and insignificant findings and to learn differential diagnostic points of each finding for the improvement of diagnostic accuracy when such cases are encountered.

The cases are to be presented in a quiz format. Each case has a literature review and differential diagnostic points. Included cases are as follows: - Contrast material (CM) filling of azygos arch valves - Nonfatal venous air embolism related to IV injection of CM - Distal thoracic duct - Axillary arch - Pericaval fat collection in IVC - Pericardial recess and sinus - Tracheal diverticulum - Focal fibroatelectasis related to spinal osteophytes - Subpleural tiny “hills” as a minor form of dependent atelectasis - Mucoid pseudotumor in the airway - Pseudothrombosis in SVC by interflowing of opacified and unopacified blood - Motion artifacts mimicking dissection of ascending aorta, bronchiectasis, or rib fracture
