Marfan syndrome is an hereditary condition which primarily affects conjunct
ive tissue with predominant vascular lesions, aortic insufficiency and aort
ic dissection which condition vital prognosis. Until further progress is ma
de in the genetic determination of the disease, the diagnosis is currently
based on the association of clinical criteria, which enables multidisciplin
ary management. This approach should lead to specific medical and surgical
treatment-which may reduce Marfan morbidity and mortality. We report the ca
se of a 45 pear-old patient with suspected Marfan syndrome during adolescen
ce. The presence of a cardiovascular lesion and a recently reported abnorma
lity ie a sacral erosion by a dural ectasia, enabled us to confirm the diag
nosis. We reviewed the current criteria in Marfan diagnosis and their speci
fic management.
