Figure 32: 44-year-old patient with new onset of diplopia and progressive loss of vision in both eyes.
a) T2w images demonstrate a subperiostal inhomogeneous lesion with smooth margins.
b) Axial ADC map demonstrates bilateral lesions (arrow). ADC-value is >1.0×10–3 mm2/s on both sides, indicating a benign lesion (histologically proven hematoma due to coagulopathy).
c) Coronal ADC map with significant distortion artifacts due to air-tissue interfaces and involuntary eye movement.
