We describe two histologically unusual cases of ependymoma of the filum terminale. Both tumors occurred in 14-year-old boys.

In case 1 the neoplasm was uniformly composed of pleomorphic giant cells and was without perivascular pseudorosettes or myxopapillary changes. Case 2 was a myxopapillary ependymoma with multiple foci of pleomorphic giant cells… CONTINUE READING
