Case 3. Schwannoma in the right nasal ciliochoroidal region in a 22-year-old woman. Compared with the brain, the tumor demonstrates isointensity on SE T1WI (A), isointensity on FSE T2WI (B), and markedly heterogeneous enhancement on postcontrast SE T1WI (C). Displacement of the right lens is seen.

Case 5. Schwannoma in the right nasal ciliochoroidal region in a 38-year-old woman. With respect to the brain, the tumor (arrow) shows isointensity on SE T1WI (A), mixed hyperintensity and isointensity on FSE T2WI (B), and markedly heterogeneous enhancement on postcontrast SE T1WI (C). Crescent-shaped retinal detachment (arrowhead) without enhancement after contrast administration is found.
