Nine chordomas of the skull base and their CT appearances are described. Destruction of the clivus and of the parasellar portions of the middle fossa are characteristic, as is calcification which may be spotty, coarse or ill-defined. The tumour is characterised by marked enhancement following contrast but, on the unenhanced CT, contrary to statements in the literature, it is hypodense or isodense with respect to cerebral tissue. The tendency to recurrence and an altogether poor prognosis is confirmed.
本文描述了9例颅底脊索瘤及其CT表现。斜坡及中颅窝鞍旁部分的骨质破坏具有特征性，钙化也具有特征性，可为斑点状、粗大或边界不清。肿瘤的特征是增强扫描后有明显强化，但在平扫CT上，与文献报道相反，相对于脑组织它呈低密度或等密度。证实了其复发倾向及总体预后较差。
