Summary
A rare orbital chondrosarcoma in a young male caused vision loss. Surgical removal successfully restored vision and resolved optic disc edema, highlighting effective treatment for this orbital tumor.
Area of Science:
- Ophthalmology
- Oncology
- Radiology
Background:
- Orbital tumors are rare, with chondrosarcoma being an uncommon subtype.
- Chondrosarcomas can affect vision and ocular motility due to their location and mass effect.
Observation:
- A 20-year-old male presented with decreased vision and proptosis of the right eye.
- Ocular examination revealed reduced visual acuity, lateral globe displacement, limited ocular movement, and optic disc edema.
- Imaging studies, including orbital computed tomography (CT) and magnetic resonance imaging (MRI), identified a space-occupying lesion in the right orbit.
Findings:
- Histopathological examination confirmed a well-differentiated chondrosarcoma (grade 1).
- The tumor exhibited characteristic features such as chondromatous cells within a fibrous stroma and binucleate cells.
- Surgical excision via an anterior approach was performed.
Implications:
- Successful surgical resection led to the resolution of optic disc edema and complete visual recovery.
- This case underscores the importance of prompt diagnosis and surgical intervention for orbital chondrosarcomas.
- Early detection and treatment are crucial for preserving vision and function in patients with orbital tumors.
