CTICasesPseudo-dissection Mimic
Imaging findings
Wispy, smoke-like artifact in the aorta mimicking a Type B dissection, caused by mass effect from a large hiatal hernia squishing the left atrium.
Key takeaways
Always consider extrinsic mass effect (like a large hernia) when seeing ambiguous "flaps" in the aorta; repeat imaging can clarify the diagnosis.
