Summary
Idiopathic orbital inflammatory pseudotumor is a rare condition that can cause significant orbital bone erosion. This case highlights the importance of considering this diagnosis in patients with orbital masses and bone destruction.
Area of Science:
- Ophthalmology
- Pathology
- Radiology
Background:
- Idiopathic orbital inflammatory pseudotumor (IOIP) is a rare condition characterized by benign orbital inflammation.
- Orbital bone erosion is an uncommon but significant feature of IOIP, often mimicking malignant processes.
Observation:
- A 56-year-old male presented with unilateral proptosis and limited ocular motility.
- Computed tomography revealed soft tissue masses with significant bone destruction in the lateral and inferior orbital walls.
- Histopathological examination confirmed the diagnosis of IOIP.
Findings:
- Surgical debulking and systemic corticosteroids led to dramatic improvement in proptosis and ocular motility.
- The patient experienced no recurrence at 6-year follow-up, maintaining excellent visual acuity.
- This case demonstrates that IOIP can present with aggressive features, including orbital bone erosion.
Implications:
- IOIP should be included in the differential diagnosis of orbital masses with bone erosion, alongside malignancy and metastasis.
- Early and accurate diagnosis is crucial for appropriate management and prevention of vision loss.
- The potential for aggressive bone destruction underscores the need for thorough histopathological evaluation.
