RESUMEN

We report an unusual case of a recurrent fourth ventricular anaplastic ependymoma with prominent chondroid metaplasia in a 16-year-old male. On initial presentation, the patient had a WHO Grade II tumor. However, at recurrence 1 year later, the tumor progressed to WHO Grade III tumor with more cellularity, necrosis and brisk mitotic activity. Chondroid metaplasia was present in both the initial and recurrent tumors.

Clinically and radiologically patient was diagnosed to have a right parietal convexity meningioma. However on histopathological examination a final diagnosis of intracranial Rosai Dorfman disease was rendered.
