ABSTRACT

Dolicho-ectasia of the left posterior cerebral artery and internal carotid artery in a 5-year-old boy is reported. There was compression of the brainstem, the mammillary bodies and the optic tract. The value of MR angiography in the diagnosis of this vascular anomaly is demonstrated. Dolicho-ectasia of more than one cerebral artery in a child is extremely rare.

ABSTRACT

We report on CT and MR image findings of a skull base chondrosarcoma. Chondroid mineralisation, a histological feature of chondrosarcoma, can be recognised on CT and is, together with the off-midline position of the tumour, the most characteristic finding. Differentiation is usually made by histological and immunocytochemical staining. Surgery, proton radiation therapy and stereotactic single high-dose irradiation have been used to treat patients with chondrosarcoma. It is worth mentioning that it was likely that the chondrosarcoma in our patient represented a malignant degeneration of an enchondroma that had been resected 30 years earlier.
