Intramural hematoma of the thoracic aorta

Clinical History

A 42 year-old male patient with hypertension and thoracic symptoms underwent, in our hospital, transesophageal echocardiography, spiral CT and MRA. The images showed a disomogeneity of the periaortic fluid, suggestive of a recent small bleeding in the context of the aortic wall.

Imaging Findings

Hypertension (220/140) was first noticed at the age of 38. Seven months ago he presented severe dispnea, feeling of heaviness in the chest and palpitation. A transesophageal echocardiography showed hiperecogeneicity of the aortic wall but there was no evidence of pericardial fluid and thoracic aortic dissection. For these reasons he underwent an MRA. The images showed a semilunar periaortic fluid area in the context of the aortic wall (hipointense in T1 W, hyperinten se in T2 W). This area was localized at the level of the descending thoracic aorta, below the origin of the left subclavian artery. To study the clinical evolution of the patient a spiral CT was also performed. The images showed a disomogeneity of the periaortic fluid. It appeared as a recently small bleeding in the contest of the aortic wall.

Discussion

In presence of an intramural aortic hematoma, spiral CT and MRA are the only techniques that allow to perform a correct diagnosis. Furthermore, these non invasive techniques provide an early diagnosis in a short time allowing, the patient to be treated immediately The accuracy of these techniques allow to choose the most useful clinical, surgical or interventional approach for the patient.
