We report a rare case of concurrent aneurysmal subarachnoid hemorrhage (SAH) and acute
aortic dissection (AAD). A 38-year-old man visited our hospital complaining of severe
headache, and brain computed tomography (CT) revealed the presence of SAH. Thoracic
to neck computed tomography angiography (CTA), performed in addition to brain CTA,
suggested a tear in the aortic arch, and subsequent CT aortography established the
diagnosis of Stanford type A AAD. The AAD in our patient, who reported no episodes
of chest or back pain, was detected incidentally by thoracic to neck CTA. The imaging
study has rarely been indicated for SAH except that it provides additional anatomical
information in patients for whom extracranial–intracranial bypass surgery or endovascular
treatment is considered. Nevertheless, our experience may highlight additional diagnostic
value of thoracic to neck CTA in SAH patients.
