FIG 2. Images in a 52-year-old woman with endophthalmitis, 5 days after intravitreal and systemic antibiotic therapy was initiated.
A, Axial precontrast T1-weighted image shows relative hyperintensity of the right vitreous body and periscleral tissue that is isointense with the brain. The findings are comparable to Fig 1A.
B, Axial T2-weighted image at the same level again shows periscleral hyperintensity surrounding the right globe. The right vitreous body and the uveal tract are now of subtle heterogenous appearance with a relative decrease in signal intensity.
C, Corresponding axial contrast-enhanced T1-weighted image again shows uveal tract and perisclearal enhancement on the right.
D, Corresponding axial FLAIR image reveals diffuse heterogenous appearance and relative hyperintensity of the right vitreous body. Periscleral tissue of similar signal intensity is also seen.
E, Axial DWI at a similar level demonstrates some relative hyperintensity of the right globe, far less prominent compared with the pretreatment image, Fig 1E.
F, Corresponding axial ADC map shows hypointensity consistent with decreased diffusion in the periphery of the right globe, which is now slightly higher than in the brain parenchyma. This area is of increased signal intensity in comparison with the pretreatment image, whereas the central portion is of slightly lower signal intensity, which is not conspicuous. The mean ADC value in the anterior and medial aspect measured 927 x 10-6 mm2/s, and in the central portion 2336 x 10-6 mm2/s. The mean ADC value in the left globe was 2813 x 10-6 mm2/s.
