Idiopathic orbital pseudotumour (IOP) is a benign orbital inflammation that can mimic other diseases. Understanding its varied imaging findings on CT and MRI is crucial for accurate diagnosis and management.

Area of Science:

  • Ophthalmology
  • Radiology
  • Pathology

Background:

  • Idiopathic orbital pseudotumour (IOP) is a rare, benign inflammatory condition affecting the orbit.
  • It can involve various intraorbital structures and occasionally extend extraorbitally.
  • The imaging characteristics of IOP can closely resemble other orbital pathologies, posing diagnostic challenges.

Purpose of the Study:

  • To present the diverse imaging appearances of histopathologically confirmed IOP cases.
  • To highlight the importance of recognizing IOP's varied presentations in computed tomography (CT) and magnetic resonance imaging (MRI).
  • To discuss the clinical features, natural history, and differential diagnosis of IOP.

Main Methods:

  • Review of imaging findings (CT and MRI) in patients with histopathologically confirmed IOP.

  • Correlation of imaging findings with clinical presentations and pathological diagnoses.
  • Discussion of differential diagnoses based on imaging characteristics.

    • Main Results:

    • IOP demonstrates a wide spectrum of imaging appearances on CT and MRI.
    • These appearances can mimic other orbital diseases, including neoplasms and infections.
    • Radiologists must be aware of these varied presentations for appropriate diagnosis.

    Conclusions:

    • Accurate interpretation of imaging is vital for diagnosing IOP.
    • Familiarity with the imaging spectrum of IOP aids in differentiating it from other orbital conditions.
    • Early and correct diagnosis facilitates timely management and improves patient outcomes.
