Magnetic resonance imaging (MRI) of his orbit and A-scan ultrasonography showed bulbar subatrophy, vitreous haemorrhage, and choroidal calcifications (Fig. 1a). A new CT scan and MRI demonstrated a mass involving his entire orbital cavity displacing the prosthesis, which reached his optic foramen and medially eroded the bone wall of his orbit and ethmoid (Fig. 1b).
