  • Title: Optic nerve/sheath enlargement. A differential approach based on high-resolution CT morphology.
    Author: Rothfus WE, Curtin HD, Slamovits TL, Kennerdell JS.
    Journal: Radiology; 1984 Feb; 150(2):409-15. PubMed ID: 6691096.
    Abstract:
    A wide variety of neoplastic and non-neoplastic processes can cause the intraorbital optic nerve and sheath to be enlarged on CT. The authors reviewed a large number of high-resolution CT scans and divided enlargement into three groups: tubular, fusiform, and excrescent. Further subdivision was possible by determining whether distinct optic nerve lucency was present or absent.
