Learning objectives
Hemorrhagic infiltration of the pulmonary artery connective sheath is a rare complication that may result in a case of acute aortic dissection,
most frequently,
Stanford type A (1,
2).
The radiological interpretation of this finding may be of a diagnostic challenge.
Multidetector computed tomography (MDCT) is the modality of choice for the diagnosis of this entity.
MDCT can also be used to monitor the evolution of this life threatening disease.
It is of great importance that radiologists can recognize and properly diagnose this complication,
since the hemorrhagic infiltration of the pulmonary artery sheath usually has a good prognosis and generally requires no specific treatment.
Thus,
our goal is to:
1.
Define the process of hemorrhagic infiltration of the pulmonary artery connective sheath secondary to acute aortic dissection,
supported by a well-established pathological correlation.
2.
Explain the pathophysiology of this entity,
including a review of the literature on this subject.
3.
Describe the radiological findings of this rare complication through a case series.
