Summary
This case report highlights a rare orbital leiomyosarcoma diagnosed using magnetic resonance imaging (MRI). MRI proved valuable for characterizing this orbital tumor, aiding diagnosis and treatment planning.
Area of Science:
- Ophthalmology
- Radiology
- Oncology
Background:
- Orbital leiomyosarcoma is a rare soft tissue malignancy.
- Diagnosis often relies on imaging and histopathology.
Observation:
- A 56-year-old woman presented with proptosis and diplopia.
- Magnetic resonance imaging (MRI) revealed an extraconal, enhancing orbital mass.
Findings:
- The orbital mass measured 2 cm and displaced the medial rectus muscle.
- Pathologic examination confirmed the diagnosis of leiomyosarcoma.
Implications:
- MRI offers crucial details for diagnosing and managing orbital leiomyosarcoma.
- This case underscores MRI's role in evaluating rare orbital tumors.
