Summary
A rare epibulbar osseous choristoma was identified in a 14-year-old girl. This unique bony growth attached to the superior rectus muscle sheath showed dense calcification on imaging.
Area of Science:
- Ophthalmology
- Ocular Oncology
- Pediatric Ophthalmology
Background:
- Epibulbar osseous choristomas are rare benign tumors.
- They typically present as solid, calcified masses in the orbital tissues.
- Diagnosis often involves advanced imaging techniques.
Observation:
- A 14-year-old female presented with a palpable mass in the upper eyelid.
- The mass was identified as an epibulbar osseous choristoma.
- Computerized tomography revealed a densely calcified, non-cystic lesion attached to the superior rectus muscle sheath.
Findings:
- The osseous choristoma was unique in its specific attachment and presentation.
- Preoperative and postoperative examinations showed no ptosis or ocular motility deficits.
- Surgical intervention was considered for the palpable mass.
Implications:
- This case highlights the importance of recognizing rare orbital tumors in pediatric patients.
- Accurate diagnosis through imaging is crucial for appropriate management.
- Understanding the anatomical attachment can guide surgical planning and predict outcomes.
