Transnasal, Transethmoidal Endoscopic Removal of a Foreign Body in the Medial Extraconal Orbital Space

Figure 1

(a–d) Frontal plain radiograph revealing (a) a rectangular high-density body (arrow) overlying the left ethmoid cells and in contact with the lamina papyracea. Contrast unenhanced axial (b) and coronal (c) CT scans show a well-delineated hyperdense body (arrow) within the left orbit, adjacent to the lamina papyracea (arrowhead in (c)) and immediately posterior to the lacrimonasal duct (curved arrow in (c)). (d) 3D-CT volume-rendered reconstructed image shows the intraorbital metallic foreign body (arrow).
