Summary:

Description
  • Radiopaedia case ID: 88281
  • Image ID: 54761732
  • Image stack position: 39/84
  • Plane projection: Sagittal
  • Aux modality: C+ arterial phase
  • Modality: CT
  • System: Vascular
  • Findings: Aortic dissection (Stanford type B) with intimal flap extending from the distal aortic arch and distal to the left subclavian artery (just lateral to its origin)  downwards along the whole descending thoracic aorta to the level just above the renal arteries. the aorta has double-lumen (both of which are well-opacified); a smaller true lumen (dense homogenous contrast within ) and a larger false lumen (lower contrast density compared to a true one) made a beak sign of aortic dissection;  It is slightly encroaching upon the origin of the celiac artery but not occluding it. No evidence of extraluminal contrast leak is seen. Bovine type aortic arch with no intimal flap is seen in the aortic arch branches. Mildly ectatic ascending aorta (44mm in diameter). Multiple calcified atheromatous plaques are seen along the abdominal aorta, at the origin of both renal arteries and common iliac arteries and showing average caliber and normal course, good contrast opacification with no evidence of aneurysm or dissection distal to renal arteries. Ancillary findings: Conclusion: Stanford type B aortic dissection.
