Day 0 (A, B) and day 2 (C, D) axial noncontrast-enhanced brain CT scans (same sections: A = C; B = D) showing moving intraventricular hyperdensities (arrows) and a cerebral infarction (star). E: hyperdensity of the left optic nerve (arrow) and the left ocular globe. CT = computed tomography.

CT-scan at admission: we observed 2 intraventricular spontaneous hyperdensities (Figure 1). At day 2, we repeat the noncontrast-enhanced brain CT scan: we confirmed the infarct in the territory of the right middle cerebral artery, but also spontaneous migrations of the intraventricular hyperdensities (Figure 1). Silicone oil was visible in the left ocular globe (Figure 1E), with a density of 98 Hounsfield units (HU), but also along the left optic nerve (Figure 1E) where the density was 75 HU (in comparison of the right optic nerve where density was only 42 HU).
