Orbital meningioma after cranial radiation for acute lymphocytic leukemia.

PURPOSE: To describe the ophthalmic findings of cranial radiation-induced orbital meningioma after acute lymphocytic leukemia therapy.

METHODS

This is a prospective clinical report.

RESULTS

We describe two patients recently evaluated with orbital meningiomas many years after cranial radiation for acute lymphocytic leukemia.

CONCLUSIONS

There will probably be more of these cases in the next several years. Unlike primary meningiomas, these neoplasms have a tendency to be more diffuse, multiple, and may undergo malignant degeneration.
