Isolated liver metastasis from sacral chordoma. Case report and review of the literature.

Chordoma is a rare malignant tumor derived from remnants of the primitive notochord. It can occur anywhere along the scull base and spine. The most commonly involved area is the sacrococcygeal region. Although chordomas invade adjacent structures, they metastasize less often. We present a case of a sacrococcygeal chordoma with liver metastasis. The nature and origin of the liver lesion was proved with fine-needle aspiration (FNA) under computed tomographic (CT) guidance.
