A rare case of optic canal lipoma caused progressive vision loss, leading to blindness. Imaging revealed adipose tissue extending from the optic canal to the optic chiasm, confirming this first reported instance.

Area of Science:

  • Ophthalmology
  • Neuroradiology
  • Neuropathology

Background:

  • Optic canal lipomas are extremely rare tumors.
  • Progressive vision loss can be caused by various optic nerve pathologies.

Observation:

  • A patient presented with unilateral, progressive, and painless vision loss.
  • Advanced imaging (CT and MRI) showed adipose tissue within the optic canal and extending to the optic chiasm.

Findings:

  • The imaging findings are consistent with an intracanalicular lipoma.
  • This represents the first documented case of an intracanalicular lipoma causing optic neuropathy.

Implications:

  • This case expands the differential diagnosis for optic canal masses and vision loss.

  • Early diagnosis and surgical consideration may be crucial for preserving vision in similar cases.
