[...]. Pneumothorax Mimic: Mach Band Artifact. CTICases. Published September 24, 2021. https://str-case-explorer.pages.dev/c/wearw
Imaging findings
Chest radiograph shows a thin, dark line at the right apical lung periphery, simulating a visceral pleural line. CT chest shows normal pleural apposition without pneumothorax.
Key takeaways
The Mach band effect is a visual perception artifact where a bright boundary appears next to a dark boundary, simulating a pleural line. Radiologists can distinguish this from a true pneumothorax by the presence of lung markings extending past the line on radiographs, or by confirming with CT.
