Non-A, non-B aortic arch dissection with atypical presentation, ambiguous CTA findings, and therapeutic dilemma

The authors aim to address the diagnostic and therapeutic challenges associated with acute aortic syndrome (AAS) when presented with atypical clinical features and ambiguous imaging findings. They report a case of a 50-year-old woman with subtle CTA abnormalities that led to differing interpretations among specialists, ultimately managed conservatively with serial imaging. This highlights the importance of maintaining a high suspicion for AAS in atypical presentations and the role of multidisciplinary approaches in guiding diagnosis and treatment.
