[Mediastinal bronchogenic cyst associated with a multiple malformation syndrome].
The authors report a case of a patient presenting with a bronchogenic mediastinal cyst, which presented as a super-infection of the cyst. The cyst was associated with malformation of the cervical vertebra, cardiovascular abnormalities and congenital deafness, placing this in the group of rare complex polymalformation syndrome with Klippel-Feil Syndrome. The authors also stress the value of computed tomography, and above all of nuclear magnetic resonance in the analysis of mediastinal tumours and in particular, of bronchogenic cysts.
