A CASE OF A MEDIASTINAL NEURENTERIC CYST DEMONSTRATED BY PRENATAL ULTRASOUND

We report the case of a posterior large mediastinal neurenteric cyst d emonstrated by prenatal ultrasound (US). Postnatal chest radiography a nd CT studies demonstrated a posterior, large cystic mediastinal mass associated with vertebral abnormalities including scoliosis, hemiverte brae and anterior spina bifida. Because postnatally respiratory distre ss developed and rapidly progressed, an emergency operation was perfor med 12 hours after delivery. The cyst was excised via right posterolat eral thoracotomy. Postoperatively, respiratory distress regressed. Thi s is the third reported case of a neurenteric cyst demonstrated by pre natal ultrasound.
