Aneurysm of the ductus arteriosus is a rare abnormality for which different
ways of pathogenesis are described. We report the case of a fatal thrombos
is of an aneurysm of the ductus arteriosus in an infant presenting feeding
difficulties and a mild dysmorphic facies. Karyotype analysis revealed a de
novo chromosomal deletion 46,XY, del (13)(q12.3,q22.3). To the best of our
knowledge, this is the first case of an aneurysm of the ductus arteriosus
associated with a chromosomal aberration.
