Craniospinal dissemination in teratocarcinosarcoma.

There have been fewer than 60 cases of malignant teratocarcinosarcoma (TCS) described in the literature, usually arising in the nose and paranasal sinuses. The authors report on a patient who presented with neurological symptoms caused by a frontal lobe TCS, and in whom widespread spinal tumor dissemination developed. In rare cases, TCSs can occur with a predominantly cranial and neurological presentation and spread to the spinal canal.
