Summary

Cribra orbitalia, sieve-like lesions of the orbital roof, can now be visualized in living individuals using computed tomography (CT). This advancement allows for further investigation into the causes of these lesions, which are often linked to anemia.

Area of Science:

  • Medical Imaging
  • Paleopathology
  • Radiology

Background:

  • Cribra orbitalia are sieve-like lesions affecting the orbital roof, historically common but recently reappearing in contemporary populations.
  • The etiology of cribra orbitalia remains largely unknown, though often associated with anemia and nutritional deficiencies.

Purpose of the Study:

  • To evaluate the efficacy of computed tomography (CT) in visualizing cribra orbitalia in living subjects.
  • To establish optimal CT parameters for imaging these orbital lesions.

Main Methods:

  • Multislice computed tomography (MSCT) was employed in both spiral and sequential modes to image a human skull with medium-grade cribra orbitalia.
  • Post-processing techniques, including virtual endoscopy and 3-D reconstruction, were utilized to generate detailed images.

Main Results:

  • Sequential MSCT mode combined with 3-D reconstruction yielded the best visualization of cribra orbitalia.
  • Optimizing threshold levels based on bone density, along with thin slice thickness and appropriate slice angle, is crucial for accurate imaging.

Conclusions:

  • Computed tomography, particularly with sequential mode and 3-D reconstruction, is a viable method for visualizing cribra orbitalia in living individuals.
  • These findings pave the way for clinical research into the etiology of cribra orbitalia using CT scans of patients.
