Cerebral radiation necrosis and radiation induced optic neuropathy


MRI features highly suggestive of a cerebral radiation necrosis with a radiation-induced optic neuropathy as well as a fatty replacement of bone marrow.

Radiation-induced optic neuropathy is considered as a common and severe ocular complication following external beam radiation therapy for nasopharyngeal carcinoma. It occurs as a result of a radiation necrosis involving the anterior visual pathway.
