Gliomas with cartilaginous metaplasia are extremely uncommon and thought to be due to metaplasia of the mesenchymal supportive elements. The tumors are located in the midline, mostly fourth ventricle and rarely in the pons. The present paper describes an unusual case of anaplastic ependymoma with cartilaginous and osseous metaplasia in a young boy which was located in the suprasellar, interpeduncular prepontine and left cerebello-pontine cistern. To the best of our knowledge, this cartilaginous metaplasia in ependymomas has been reported only thrice.
