MRI imaging (T2 images, sagittal view) at presentation (a) and during follow-up (b) 5 weeks of TMP-SFX twice daily; (c) 20 weeks follow-up, of which 6 weeks of TMP-SFX 4 times a day and 14 weeks twice daily. Gradual improvement of the lesion was seen during treatment (highlighted by arrow).

A 1.5 cm contrast-enhancing lesion in the left basal ganglia area was detected with significant perilesional oedema and limited mass effect with narrowing of the trigonum of the left lateral ventricle (Figure 1(a)).
Ocular features at presentation and during follow-up. (a) The left eye showed a white retinitis lesion along the superotemporal arcade (colour fundus picture). (b) Adjacent Kyrieleis arteritis (arrow) and ischaemia on fluorescein angiography at first visit. (d) Optical coherence tomography demonstrates the full-thickness retinitis (arrow) with limited adjacent vitritis. (c) With treatment, the lesion gradually became atrophic ((e) 2 months follow-up) and vascular supply was restored via a collateral artery.

Fundus examination disclosed a small midperipheral white retinitis lesion in the right eye and a larger retinal necrotic lesion in the left eye with associated Kyrieleis arteritis (Figure 2(a)). The retinitis lesions in both eyes gradually became atrophic (Figure 2(c)).
