Penetrating aortic ulcers after absorption of intramural hematoma.

We report a case of a type B aortic intramural hematoma, which rapidly expanded, with ulcer-like projections, after complete absorption of the hematoma. One month after the initial presentation, a new computed tomographic scan showed the appearance of a thin ulcer-like projection in the aortic wall. Three months later, after the patient reported a new episode of chest pain, a computed tomographic scan revealed 2 penetrating ulcers and rapid aortic dilation; the aortic hematoma had been completely absorbed. Urgent thoracic aortic replacement was undertaken. Three years postoperatively, the patient was asymptomatic, with no lesion or dilation of the aorta upon computed tomography. After an acute hematoma, the strength and structure of the aortic wall can alter rapidly. Damage and weakening of the aortic wall are caused mainly by infiltration of inflammatory cells, which have pronounced proteolytic and elastolytic activity. Due to the unstable nature of the lesion, optimal management remains controversial. In our patient, the inflammatory process led to the development of 2 aortic ulcers and aortic dilation within 3 months of the acute lesion, requiring urgent surgical intervention.
