MRI of orbital schwannomas.
The literature on MRI of orbital schwannomas is limited. The appearances in three patients with an orbital schwannoma were reviewed. A superior orbitotomy through a subfrontal craniotomy revealed a schwannoma in all cases. MRI characteristics of very low signal on T1-weighted images and homogeneous postcontrast enhancement may be helpful for differentiating schwannomas from other intraconal masses.
