Key result
CT pulmonary angiogram misses acute type A aortic dissection detected by echocardiography and gated CTA.
Why the study?
The limitations of CT pulmonary angiography in detecting acute aortic dissection and the importance of accurate diagnosis in acute chest pain were highlighted by this case.
Case Report (n=1)
This case highlights the limitations of CT pulmonary angiography in detecting aortic abnormalities and emphasizes the importance of appropriate imaging modalities when aortic dissection is suspected.
CTPA missed type A dissection in this case; leaves open whether gated CTA should supplement standard protocols in select high-risk patients.
We report the case of a young man with a history of abdominal aortic aneurysm repair who presented with acute chest pain. An initial work-up included a computed tomography (CT) pulmonary angiogram, which ruled out pulmonary embolism but did not reveal an aortic dissection. Subsequent transthoracic echocardiography and gated CT angiography confirmed an acute Stanford type A aortic dissection. This case highlights the importance of considering aortic dissection in differential diagnoses and the limitations of CT pulmonary angiography in detecting aortic abnormalities.

Ellauzi et al. (2025) conducted a case report in Acute Stanford type A aortic dissection (n=1). Computed tomography (CT) pulmonary angiogram vs. Transthoracic echocardiography and gated CT angiography was evaluated on Detection of aortic dissection. An initial CT pulmonary angiogram failed to detect an acute Stanford type A aortic dissection, which was subsequently confirmed by transthoracic echocardiography and gated CT angiography.
