FIG 5. Scalar asymmetry with LEDS.

A, Axial T2-weighted FSE MR image of the left inner ear in a patient with LEDS shows enlargement of the anterior scalar chamber (arrow). The anterior chamber is composed of the scala vestibuli and scala media. The endolymphatic sac (asterisk) is markedly enlarged.

B, Axial image 2 mm below A also shows asymmetric enlargement of the anterior chamber (arrow). The posterior chamber (arrowhead) comprises the scala tympani, which is normal in size. Asterisk indicates endolymphatic sac.
