Congenital absence of right abducens nerve presenting as Duane retraction syndrome
Congenital absence of right abducens nerve presenting as Duane retraction syndrome
Serial 3D-SPACE axial MRIs from caudal (A) to cranial (D) show normal left abducens nerve. In this syndrome, abducens nerve can be absent or hypoplastic. Arrows indicate the anterior pontine arachnoid membrane. Dashed arrows indicate the left abducens nerve.
3D: three-dimensional; SPACE: sampling perfection with application-optimized contrasts using different flip angle evolution; MRI: magnetic resonance imaging.
