Case 1. Upper row, left: dystopic prosthesis and poor cosmesis before surgery. Upper row, middle: intraoperative finding of the RTV silicone implant removed by the skin crease approach. Upper row, right: the findings are confirmed in a colored 3D reformation of the surface-shaded image (the white arrow indicates the implant and the black arrow indicates the silastic material). Lower row: the axial and coronal CT scan (bone window) shows dense material along the extraconal space of the right orbital cavity adjacent to the right orbital roof and lateral orbital wall (black arrow) with rarefaction along the inner table and minimal hyperostosis (dashed black arrow).

The socket was inflamed, grade 3, with mild redness and copious discharge (fig. 1; upper row). Allergan Inc., Dublin, Ireland) with no benefit. A CT scan of the orbit showed dense material along the extraconal space of the right orbital cavity adjacent to the right orbital roof and lateral wall with rarefaction along the inner layer and minimal hyperostosis (fig. 1; lower row).

Case 2. Upper row, left: preoperative status of the socket (grade 4, inflamed, contracted). Upper row, right: intraoperative RTV orbital implant, removed by the skin crease approach. Lower row: coronal and axial CT scan (bone window) showing a dense irregular mass originating from left orbital roof muscles (black arrow), associated with adjacent inflammatory changes in the extraocular muscles (white arrow).

CT scan and magnetic resonance imaging (MRI) indicated an irregular foreign body located in the left orbital roof, associated with adjacent inflammatory changes involving the extraocular muscles (fig. 2).
Pathology slides; tissue around the orbital foreign body. a Fibrosis (F) and granulomatous inflammation (INF) surrounding an empty vacuoles. H&E x10. b Empty vacuoles (arrow) surrounded by histiocytes and foreign body giant cells (arrowhead). H&E x20.
