Orbital vascular lesions encompass various types like hemangiomas and fistulae, originating from diverse sources. Imaging techniques such as computed tomography and magnetic resonance imaging are crucial for diagnosis.

Area of Science:

  • Ophthalmology and Radiology
  • Neuroimaging of Orbital Lesions

Background:

  • The orbit contains a variety of vascular lesions, including hemangiomas, lymphangiomas, dural arteriovenous fistulae, aneurysms, varices, and hematic cysts.
  • These lesions exhibit heterogeneous origins, reflecting their diverse pathological nature.

Purpose of the Study:

  • To review the spectrum of vascular lesions found in the postbulbar orbital region.
  • To discuss the diagnostic imaging modalities employed for these conditions.

Main Methods:

  • Review of imaging findings for various orbital vascular lesions.
  • Utilization of cross-sectional imaging, primarily computed tomography (CT) and magnetic resonance imaging (MRI).
  • Consideration of specialized CT/MRI techniques and selective arteriography for specific indications.

Main Results:

  • Computed tomography and magnetic resonance imaging are the primary tools for evaluating most postbulbar orbital vascular lesions.
  • Advanced imaging techniques and arteriography are reserved for complex or specific diagnostic challenges.

Conclusions:

  • A diverse range of vascular lesions can affect the postbulbar orbit.
  • Standard and advanced cross-sectional imaging play a vital role in the diagnosis and characterization of these orbital pathologies.
