MELA, Martín et al. Multidetector CT in diagnosis of aortic pseudocoarctation: Two reported cases and revised literature. Rev. argent. radiol. [online]. 2011, vol.75, n.2, pp.91-95. ISSN 1852-9992.

The aortic pseudocoarctation is a rare anomaly characterized by a tortuous elongation with kink aorta which compromises the distal portion of the aortic arch and the proximal descending portion, typically related to the insertion site of arterious ligament. Usually, there are no associated symptoms so the diagnosis is generally incidental with imaging such as Multidetector Computed Tomography (MDCT) or Magnetic Resonance Imaging (MRI). It differs from the true aortic coarctaction in their morphology and in the absence of hemodynamically significant obstruction. In this paper we review the imagenologic features using MDCT in two patients who were diagnosed with pseudocoartaction, which was not suspected before performing the study. MDCT allows a proper diagnosis showing differential characteristics with other aortic anomalies.
