title: A case of amyoplasia in a monochorionic twin pregnancy: a sequela from twin-twin transfusion syndrome?
abstract: OBJECTIVE
  To present and discuss the sonographic and clinical findings in one twin of a monochorionic pair affected by amyoplasia.
  
  
  METHODS
  On ultrasound examination at 21 weeks in a monochorionic twin pregnancy, twin I was smaller, hydropic, with multiple contractures consistent with amyoplasia and oligohydramnios. Twin II was anatomically normal with polyhydramnios.
  
  
  RESULTS
  The twins were delivered at 28 weeks' gestation. The clinical findings were consistent with twin-twin transfusion syndrome (TTTS).
  
  
  CONCLUSIONS
  It is postulated that TTTS may be a causative factor in the excessive incidence of amyoplasia in monozygotic twin pregnancy.
