Lateral Rectus Palsy in A Case of Mediastinal Yolk Sac Tumour

Aims: To report a case of mediastinal yolk sac tumor with distant metastasis and isolated, right lateral rectus palsy.

Settings and design: Case report.

Methods and material: A 16-year-old male with history of left sided knee swelling for 3 months and inward turning of right eye for 20 days underwent a thorough ophthalmic examination followed by imaging investigations and serology.

Results: Lateral rectus palsy in this case may be idiopathic or it may be because of CSF metastasis. In the present case, the tumor was originally thought to be osteosarcoma of knee. But the isolated right rectus palsy without any other ophthalmological sign prompted thorough investigations. The imaging investigations thus initiated revealed the primary tumor to be a mediastinal yolk sac tumor with distant metastasis.

Conclusions: Isolated lateral rectus palsy in a known case of tumor should be properly evaluated with appropriate imaging techniques and investigations.
